Georgia Tech was rated No. Instead, it rewards teams that do well against good opponents.

Both teams are among the 7 worst Division I-A teams in the country, joining Louisiana-Monroe, Rice, Duke, Utah State and Florida International.
The Sagarin College Football Ratings: What They Are, How to Read Them and What to Do With Them
by: Ed Bagley
For those who wager, it may be helpful to put some science on your side when you wager, and one of the best places to do that is with the Sagarin College Football Ratings.
Anyway, the Sagarin rating is a numerical measure of a team’s strength.
5) Notre Dame, beaten badly (33-3) by Georgia Tech, was rated No. Good luck, La Salle, and God speed.
If there is a way for the NCAA to assert its superior power, it does so by making everything more difficult and confusing, similar to your United States government and its IRS tax code which could reduce a sane person to tears just reading it.
Following the first week of college football action, here are some facts that interested me about Sagarin’s first-week ratings:
Folks in the gaming business know that more than a billion dollars is wagered on every Monday Night Football game during the season.
Only Division I (both A and AA) are counted for rating and schedule strength during the season.
While betting on sports is only legal in a few places in the United States, such as Las Vegas, millions of office workers are involved in sports pools every week now that the football season has arrived.
The BCS (Bowl Championship Series) does not factor in scoring margin. 57 after the loss. 38 following its upset of mighty Michigan 34-32 on Michigan’s home field. 145 after its opening loss) face off in week two. 36 after steamrolling over UAB 55-18 in its home opener.
Michigan was ranked No. 2. 174 (56 AA teams are rated better), and their play reflects their rating. Now you can better understand why La Salle College is ranked last among 242 Division I schools.
4) Wyoming, a small school and never among the nation’s top teams, was ranked No. The Explorers next job will be to actually win a game. The worst-rated A school is Florida International at No. The home edge will vary during the season.
Created by Jeff Sagarin, a 1970 MIT mathematics graduate, these computer ratings are for Division I-A (what the NCAA now calls the Football Bowl (FB) Subdivision) and Division I-AA (what the NCAA now calls the Football Championship (FC) Subdivision) teams.
Ursinus College is not a Division 1 school (which includes the 242 teams with La Salle), not a Division II team (which includes another 157 teams), but a Division III team

In the online casino world meeting people from all over the world is a possibility
Mike Seba is a Senior Oddsmaker at LVSC and has been making lines for the last six years. In doing so they attempt to make more attractive the team that is getting less action. We do this by drawing from past experiences and applying them to current situations.
“The main objective is that our clients get equal action on both sides,” Seba said. “We’re not trying to pick the team that covers the spread, we’re trying to make it a coin flip, a tough decision (for the bettor).
What Is the Line Trying to Accomplish?
The purpose of these adjustments, like all line adjustments, is to more equally divide the betting action.
Divided action means the sportsbook is guaranteed a profit on the game because of the fee charged to the bettor (called juice or vig – typically $11 bet to win $10). For example, the public might have heavy betting interest week after week on a popular college football team such as USC. If we’ve done that, we’ve done our job.”
Moving the line is the oddsmaker’s effort to balance betting action, and often times such moves can have a major impact on a bettor’s decision. If an oddsmaker comes up with a preliminary line of USC -7, then an adjustment up to -7.5 or -8 would be made in response to the public’s expected USC bias.
Oddsmakers can also change the line depending on various event-related factors such as player injuries or weather. Also, adjustments are made after reading each team’s local newspapers to get a sense of what the coaches & players are thinking going into the game. Power ratings are the oddsmaker’s value of each team and are used as a guide to calculate a “preliminary” pointspread on an upcoming game. In our extended interview, Seba explained that there are 4-5 oddsmakers assigned to make lines for each of the major sports (pro & college football and basketball; MLB, NHL, boxing, golf). Examples of non-game factors that would require an adjustment to a team’s power rating are key player injuries and player trades. Obviously, if the line comes out a week ahead of the event (which is the case in football), there is much that could happen during the week leading up to the event that could affect the line. Each of these oddsmakers bring unique opinions, strengths and weaknesses to the process.
Individual books having players who consistently bet with certain tendencies (such as an extreme bias toward favorites or toward a certain popular team like USC)
“You either have a passion for it or you don’t,” Seba said. This usually includes having up-to-date power ratings on each team. That is not the case at all – their intent is NOT to evenly split the ATS result between the teams; rather, their goal is to attract equal betting action on both sides. Oddsmakers have to determine if any changes are necessary and send out an “adjusted line.”
Once a game’s power rating based pointspread is determined, the oddsmaker will make adjustments to that line after considering each team’s most recent games played and previous games played against that opponent. The power ratings are adjusted after each game a team plays. Seba explained that it all starts with each oddsmaker creating a line on each game based upon their own personal approach.
The last step in the line-making process for each oddsmaker is taking one final look to determine whether or not the line “feels right.” This is where common sense and past experience with how games are bet enters into the picture.
How the Opening Line Is Made
Once the opening line is released by LVSC, the individual sportsbooks decide if they want to make any adjustments before offering it to the public.
There is a common misconception that point spreads represent the oddsmakers’ prediction of how many points the favorite will win by.
Oddsmakers at LVSC are professional sports junkies who love what they do and would probably do it for nothing if you asked them, but they do get paid for it.
For example, if the pointspread on a game is 7 and most of the money is coming in on the underdog (taking the +7), sportsbooks will then move the number down to 6 ½ to try and attract money on the favorite. Of the 4-5 oddsmakers, generally the 2 most respected opinions are weighed more heavily by the Odds Director before he decides on the final line.
Las Vegas Sports Consultants (LVSC) is the world’s premier oddsmaking company and the most respected authority on making the lines.
Since the oddsmaker’s ultimate goal is equally dividing the betting action, public perception and betting patterns must be taken into account. By moving the line, sportsbooks can influence how the public bets on a particular game. Reasons for such adjustments include:
Experts working for the individual books having a strong opinion on the game
“The #1 thing for us is to make a line for each game that creates good two-way action. Of course there is an entire method to the madness on how the opening line is created. Stated another way, they want to create a line that half the people find appealing to bet one way while the other half find it appealing to bet the other way (known as ‘dividing the action’). By necessity their approach is very research-oriented and concise, since with millions of dollars at risk there is little margin for error.
Why the Line Changes
The opening line is the first line created by the oddsmakers, which is then sent out to sportsbooks.
A round-table discussion among the 4-5 oddsmakers involved in making the line for each sport is then conducted and a consensus line is decided upon by the Odds Director before it is released to the sportsbooks. People think it’s much more complicated, but it’s not.”
Once betting begins, sportsbooks can adjust the line at any time

He wasn’t aware of any other possible legal sanctions.
An online sportsbook said it has dropped betting on CBS’ “Survivor” after allegedly finding that network employees were wagering – and winning – on the hit reality show.
The Costa Rica-based BoDog.com found at least two CBS employees betting on the show’s outcome, said BoDog spokesman Lance Bradley. The show narrows the field to two finalists in filmed competitions. One person was said by BoDog to work in a “production role” for CBS.
The players’ current bets on “Survivor: Amazon” have been canceled and their money refunded, Bradley said. The winner is unknown until he or she is chosen in a vote by other contestants during a live broadcast.
For the current “Survivor,” the bets in question affected the odds for contestants Jenna Morasca of Pittsburgh, Pa., and Matthew Von Ertfelda of Washington, D.C.
Betting on events other than sports or racing is banned in Las Vegas sportsbooks, a spokeswoman for the Nevada Gaming Control Board said Thursday. The suspicion is they had insider knowledge, he said.
By Lynn Elber
“Throughout the history of ‘Survivor,’ many have believed they knew the outcome of the show,” Ender said. All Rights Reserved. The biggest payoff, $8,000, came on a $1,000 bet placed on the fifth “Survivor” at 8-to-1 odds.
At least two players have been identified as CBS employees and other names may be connected to the network or may be aliases, Bradley said. Most offshore sportsbooks accept such alternative bets, said BoDog’s Bradley.
BoDog requires that bettors must not have knowledge of an event’s outcome. Bradley said that bets taken from those alleged to be with CBS skewed the odds significantly on “Survivor” contestants.
They wagered correctly on who would be the final two contestants in both the fourth and fifth editions of “Survivor,” Bradley said
Here are some useful tips regarding lifestyle changes to get rid of a gambling addiction.
. Study results show that a gambler who has not been treated for compulsive gambling during his desperation phase is likely to commit suicide. Addiction to gambling at a young age increases the risk of suicide. ‘Problem gambling’, also known as ‘ludo mania’, can destroy the life of the gambler and also of his/her family members. Despite being aware of the serious negative consequences, or despite having a strong desire to quit, he cannot stop himself from gambling. He lies to his family and friends, borrows money, and loses control over his mind and behavior. When a gambler with severe ludo mania meets certain criteria, the condition is diagnosed as ‘clinical pathological gambling’. To experience the same excitement, he needs larger wagers or more frequent gambling.
There are chances that he has other psychiatric problems at the same time; for example, substance use disorder, mood and anxiety disorder, personality disorder, etc. Researchers have noticed increased rates of mental health disorders in gamblers with severe ludo mania. Gambling addiction is referred to as ‘compulsive gambling’ or ‘impulse-control disorder’, where the behavior of the gambler is similar to that of a person who has substance addiction.
When an individual realizes that gambling is destroying his family and social life, he thinks of quitting, but in just a few hours or within a couple of days, he is again found in a gaming zone or casino. As he spends more gambling, he requires more money to recover his losses. He may lose his job and may commit crimes to get money for gambling. Analysis of casino customer data may help identify problem gamblers, but casino owners do not share this data for fear of losing their most lucrative customers (may be 25 – 50%). But studies show that suicide attempts are usually made by older people with problem gambling

The critics have chimed in on the new Nicholas Jarecki-directed film, with Rotten Tomatoes giving “Arbitrage” a very respectable 81 percent rating. But why grade on a curve? Every episode of ‘Law & Order’ I’ve ever seen has a more complicated and plausible plot, punchier dialogue and more New York authenticity, all in less than half the time consumed by this poky would-be finance thriller.”
Peter Debruge of Variety: “Between this cast and the conviction Jarecki brings to the table, the film feels incredibly accomplished for a first feature.”

Roger Ebert of The Chicago Sun-Times: “Hitchcock called his most familiar subject ‘The Innocent Man Wrongly Accused.’ Jarecki pumps up the pressure here by giving us a Guilty Man Accurately Accused, and that’s what makes the film so ingeniously involving.”

Peter Travers of Rolling Stone: “Richard Gere’s performance in the sinfully entertaining ‘Arbitrage’ is too good to ignore…he is at the peak of his powers.”
See what else critics are saying:
(CBS News) Richard Gere is back in the shoes of an investor powerhouse, portraying fictional New York hedge fund magnate Robert Miller in “Arbitrage,” which hits theaters today. Gere, allow me to apply a little buzzicidal ointment. Gere and Sarandon previously appeared together on the big screen in the 2004 romantic comedy “Shall We Dance.”
Christy Lemmire of The Associated Press: “Gere is so charming, so irresistible when he’s on top of the world – when he’s got all those plates humming in unison – that he kind of makes you root for his character to get away with it all.”
But not everyone agrees.
The 63-year-old “Pretty Woman” actor stars alongside Susan Sarandon and Tim Roth in the drama about a man desperate to complete the sale of his trading empire. Pols of TIME: “The main reason to see ‘Arbitrage’ is Gere, whose steady improvement with age (he just turned 63) is not remarked upon enough.”
. Gere is one of cinema’s great walkers, graced with a suggestively predatory physical suppleness, and he slips through the movie like a panther. Clint Eastwood’s chair has a better shot at an Oscar nomination.”
Kyle Smith of The New York Post gave it 2 out of 4 stars: “‘Arbitrage’ is a decent enough way to spend your time compared to, say, waiting on line at the grocery story.
Gere has attracted attention for his acting in the film, with Manohla Dargis of The New York Times noting, “Mr. He’s the film’s most deluxe item.”

Good tips can encourage great customer service. Many people feel if they hit a jackpot, regardless of the size, they should tip the slot attendant because he or she was the one that paid out the jackpot.
In todays world the casino could just as easily have the machine spit out a ticket and then I could take it to the cashiers’ cage to redeem my earnings. As For Slot attendants, the only thing they can do is be rude too you. I also do not have to stumble with placing 2-3 quarters in her hand each time she brings me a new drink.
Others suggest that tipping the slot attendant is a waste of money and will never do it. A lot of their income is based on tips. The cocktail waitresses, the slot attendants, and all other casino personnel have no incentive to be friendly, prompt, and courteous to the casino patrons.
If I have to tip a slot attendant to keep him or her happy then I will simply spend my money elsewhere. Did the slot attendant pitch in on the money I put in the machine? No. The problem though, is that in order to survive the slot attendant needs to receive tips.
A slot attendant always needs to be polite and courteous to players regardless of whether they receive a tip or not. They point many customers to many different machines.
Their have been casinos in the past that have tried a no tipping policy.
It is a scam. These people feel that the only thing the slot attendant did is put a ticket in the machine and count out your cash.
If you feel that you have received excellent customer service in a casino and want to tip the person or people, then go right ahead. Casinos want players to keep playing after they win a jackpot, not pack up and move to a competitor’s casino.
If you win a jackpot and don’t tip the slot attendant, and then receive poor and rude service from the slot attendant, quit playing. Out of all of these customers, one may hit a jackpot. They can get you paid out faster, and they will let the cocktail waitresses know that you tip so your drinks will come more often without waiting.
Yes, You Should Always Tip the Slot Attendants
Slot Attendants generally work for minimum wage. It is very hard to survive in Las Vegas on minimum wage.
Tipping is very personal, at the restaurant if you are not a regular tipper but you always eat there, then be prepared to have mucus in your food. The customer then thinks they won because the slot attendant pointed them too the machine originally. I may have lost $700 before I won the jackpot. The slot attendants do not know any better then you do which gaming machines are the best too use. Every time those casino policies have failed. Did the slot attendant give me money last week when I lost money?
If this happens multiple times a casino will then either retrain the slot attendants in customer service skills or fire them.
Just because I won a $500 jackpot does not mean that I am ahead $500. On the same token, if you feel a customer does not receive a tip then do not tip them. Slot attendants do not deserve a tip and never have.. Explain to them how you won a mini-jackpot and was going to keep gambling here but instead you are taking your winnings to a different casino to play because you are tired of the slot attendant who is very rude too you, simply because you did not give her a tip.
The slot attendant will then stare at you, hoping for tip. Instead, the casino wants to verify that the win is authentic, and then have the slot attendant pay me my winnings.
The debate has raged on for years. I don’t think so.
Many people who like to tip say “well the slot attendant pointed out the good machines too use”. Cash out your machine and find a floor supervisor or manager. You should never feel forced to tip a slot attendant. That means I am still down $200, and the slot attendant wants a tip. It is all luck.
Further Thoughts on Slot Attendants
Whether you choose to tip the slot attendants or not is a very personal choice. Here are both sides to the story.
Tipping slot attendants is simply the right thing too do.
The debate on whether you should tip your slot attendant or not rages on. For what? The slot attendant did nothing but take 3 minutes of her time to pay me my earnings. Most of them will lose. If you go to the same casino to play on a regular basis, a repeat customer, then you should always tip the slot attendants. I tend to give a large tip too the cocktail waitress the first time I see her. Maybe in the old days, before all of this new computer generated tickets, I would consider tipping the slot attendant. You should decide for yourself whether you want to tip a slot attendant. They can point you out too machines that tend to pay off more often. Image Credit: (Flickr/sophistechate)

All Day Long Buffets In Las Vegas
No, Don’t Ever Tip the Slot Attendants
I gamble my own money, I get lucky and win $500, and now I am suppose to tip the slot attendant who simply paid me the cash? It is a scam. Each night the slot attendants play a game of numbers.
As for the other casino staff such as cocktail waitresses and blackjack dealers, if you tip or not is up too you. If your slot attendant is rude, cash out, talk to a floor supervisor, and then move onto a new casino.
The casinos that have tried to the no tipping policy have paid higher than minimum wage to their workers, but it was still not enough.
Most slot attendants will tend to be courteous, even if you do no tip them. I then usually receive many drinks and get them without waiting. I call hors manure on that

In Britain, a practice has developed in which highly experienced “key men” employ others to place bets on their behalf, so as to avoid detection and increase accessibility to retail bookmakers and allow the financiers or key arbitragers to stay at a computer to keep track of market movement.
There are a number of potential arbitrage deals. While making deposits is usually made easy and quick, making withdrawals often requires proof of identity in the form of passport/driver license, copies of which need to be shared with the bookmakers via fax/email or even postal mail, which causes additional identity theft risks. Marshall The Quarterly Review of Economics and Finance 49 (2009) 917-930

Other potential problems include:
Arbitrage is an extremely fast-paced process and its successful performance requires lots of time, experience, dedication and discipline, and especially liquidity.
Placing a bet of $100 on outcome 1 with bookmaker 2 and a bet of $100*1.43/3.9=36.67displaystyle $100*1.43/3.9=36.67 on outcome 2 at bookmaker 1 would ensure the bettor a profit.
For instance if one places a bet on outcome 1 at bookmaker 2 and outcome 2 at bookmaker 1:
Or in other words, if there are two outcomes, a 1/1 and a 2/1, by covering the 1/1 with $500 and the 2/1 with $333, one is guaranteed to win $1000 at a cost of $833, giving a 20% profit. Many bookmakers may now be using shared security servers in order to pinpoint people suspected of arbitrage betting; they can simply limit stakes to make arbing unprofitable and even close accounts without honoring a bet that was placed. Traders are often attracted to high odds comparison sites that yield high percentage profits per stake (5-30%); this is often used by hackers to lure a high number of arbitrage bettors that then place large sums of money on these arb’s, only to lose all of the profit and even entire savings in bank accounts to hackers or untrustworthy websites, which may further use the gathered data to sell personal data to criminals.
Making errors as an arber: In the excitement of the action and due to the high number of bets placed, it is not uncommon to make a mistake (like traders on financial markets). When conditions allow, by placing one bet per each outcome with different betting companies, the bettor can make a profit regardless of the outcome. If one wishes to place stake s1displaystyle s_1 at outcome 1, then one should place s2=s1*o1/o2displaystyle s_2=s_1*o_1/o_2 at outcome 2, to even out the odds, and receive the same return no matter the outcome of the event.
By signing up to various bookmakers, it is possible to turn these “free” bets into cash fairly quickly, and either making a small arbitrage, or in the majority of cases, making a small loss on each bet, or trade. In theory a trader could turn a small investment into large profits by re-investing his earlier profits into future bets so as to generate exponential growth.

Arbitrage using only the back or lay side might occur on betting exchanges. all outcomes) of an event, whose implied probabilities add up to less than 1. In the bettors’ slang an arbitrage is often referred to as an arb; people who use arbitrage are called arbers.
Bookmakers generally disapprove of betting arbitrage, and restrict or close the accounts of those who they suspect of engaging in arbitrage betting. For example, one could actually make more money by placing the “wrong” bet where the outcome happens to be beneficial, though not justified by the arbitrage calculation. This usually leads to unprofitable arbing as the most successful bookmakers are so adept at identifying arbitrage bettors.
Stake reviewal: Some bookmakers are known to accept only very small stakes by default, while requiring larger stakes to be manually reviewed before being accepted, which basically makes it difficult for an arbitrage better to determine if a leg was completely accepted or not, until it may be too late.
Bet cancellation: If a bettor places bets so as to make an arbitrage and one bookmaker cancels a bet, the bettor could find himself in a bad position because he is actually betting with all the risks implied.

For example, the appropriate stakes may be incorrectly calculated, or be placed on the wrong “legs” of the arb, locking in a loss, or there may be inadequate funds in one of the accounts to complete the arb. Arbitrage betting is almost always insufficiently profitable due to detection, unreliable betting websites, limiting of stakes, hackers, and scammers that use high percentage arbitrages to trick bettors into providing security credentials.

For an individual bookmaker, the sum of the inverse of all outcomes of an event will always be greater than 1. Usually these gaps will be in the order 8 – 12%. It is in principle the same as the arbitrage using different bookmakers. However, repetition of this stroke of luck is unlikely, assuming the bookmaker has calculated the odds so they make a profit. In some sports different bookmakers deal with outcomes in different ways (they differ in their handling of – for example – player withdrawal due to injury in tennis, overtime in ice hockey), meaning that both “legs” can lose.

Withdrawals are often limited to a certain amount per month or to a certain number of free withdrawals per month
Withdrawals are often charged for, not just on the side of the bookmaker, but sometimes also on the ewallet side (transfer to the bettor’s bank account).
In some countries, additional costs are imposed by government taxes, so that the final profit is further reduced by a fixed percentage of say 5% (Germany/Europe).
Professional arbitrage betting may eat up considerable time and energy and requires lots of experience and liquidity, as well as sufficient funds to recover from inevitable losses that will happen sooner or later due to the aforementioned reasons.
Typically, arbitrages have a profit margin of only 2-5% – many other arbitrages are regarded as “high risk” (“palps”). However, the commission charged by the bookmakers and exchanges must be included into calculations.
