	Trading Systems With a High Winning Percentage
		Obviously the higher the winning percentage the less likelihood of stringing together a long series of trades with only occasional winners.
		If we can design a system that has a low average loss and a high winning percentage we are looking at a system that should be very drawdown resistant.
		However if we are trading a system with a high winning percentage we have much less need for diversification.

	Win (baseball) - Wikipedia, the free encyclopedia
		In baseball, a pitcher is credited with a win (or "W") when, in a game won by his team, he is the team's pitcher at the time that his team takes a lead that it does not relinquish for the remainder of the game.
		If his team takes a lead it does not relinquish while that pitcher is in the game, the win is awarded to the relieving pitcher who, in the judgment of the scorer, pitched the most effectively.
		Winning 25 or more games is now considered one of the highest marks of extreme success and excellence in the sport, on a par with winning 30 or more games a generation or two ago.

		Winning percentage of each team vs. the first-place team, or their composite winning percentage against any teams tying for first place.
		Winning percentage of each team vs. the second-place team, or their composite winning percentage against any teams tying for second place.
		This process continues as necessary, comparing winning percentages of teams in the tie vs. the second-place team or their composite percentages vs. teams tying for second place, third place, etc., until all ties are broken and seeding is complete.

	Canuck Winning Percentage Graphs (Site not responding. Last check: 2007-11-04)
		In the second half of January, the Canucks rattled off six wins in a row, literally pushing their winning percentage off the chart.
		Their ten game winning percentage at game 51 is an amazing 0.850 (17 points in 10 games).
		Wins are indicated on the graph by "W", overtime wins by "OW", losses by "L", overtime losses by "OL" and ties by "T".

		The first step is to define the total variance in winning percentages to be a combination of the variances of luck and ability.
		The team's true ability, or winning percentage for the rest of the season is the solution to the cubic equation above.
		To test the accuracy over a wide range of games and winning percentages, I regressed the average rest-of-season winning percentage against P for each set of games and wins, where the number of games is divisible by 5 and is between 19 and 121.

	Notes on My RPI Calculations
		A team's RPI is a sum of three values: 25% of the team's winning percentage, 50% of its opponents' average winning percentage (strength of schedule), and 25% of its opponents' opponents' average winning percentage (opponents' strength of schedule).
		A similar adjustment used to be made to remove each team's wins and losses from its opponents' opponents' records before calculating its opponents' opponents' winning percentage.
		We can either (A) add up the wins and losses of all opponents (after adjustments) and calculate the percentage of wins, or (B) calculate each opponents' winning percentage separately and then average the results.

	FuturesBuzz.com/Trading Article 1
		Although it is not essential for a system to have a high winning percentage in order to make money, there are many advantages for those systems where the frequency of profitable trades exceeds the losers.
		Also, with a high winning percentage we can be more optimistic about starting with less capital and using our profits to build up our capital prior to any major drawdown.
		On the other hand, if we set out to have a high winning percentage we can obtain it without sacrificing much, if anything, in the way of profits and we will create a system that is extremely "user friendly" and reliable.

	2003-2004 Ratings Percentage Index
		The Opponents' Winning Percentage (OPct) for a team is calculated by averaging the winning percentages of all their opponents in games not involving that team.
		The Opponents' Opponents' Winning Percentage (OOPct) for a team is a weighted average of the Opponents' Winning Percentages (OPct; q.v.) of each of their opponents.
		One ranking system which, like the RPI, considers only a team's overall winning percentage and the strengths of the teams they played, is the Bradley-Terry ranking system, which goes under the name of KRACH when applied to college hockey.

		Our conclusion is that while a rise in each stat had some affect in the rise or fall of winning percentage, we could not determine a single stat that had a direct affect on the dependent variable (Winning Percentage).
		The dependent variable is winning percentage, and the stats we measured were selected as the independent variables.
		The study does suggest that the independent variables considered as a whole could be used to predict winning percentage but this is an obvious result.

	JoBS: Binomial Individual Winning Percentage Method
		One of them, floor percentage, is an estimate of the percentage of times a player contributes to his team scoring.
		Since offensive rating looks at points and floor percentage looks at the number of scores per possessions, something not as "bottom line" as points, it is natural to use offensive ratings as a better evaluator of talent than floor percentage....
		The program uses an individual's floor percentage and their offensive rating to simulate how often they outscore a hypothetical opponent using the same number of possessions in a game as they do.

	Football Ratings
		The Performance Against Pythagorean Winning Percentage uses the PWP instead of winning percentage, and the Generalized Performance Against Algorithm to derive a strength of schedule with respect to PWP.
		The Pythagorean Winning Percentage is a measure of a team's ability to score (and prevent opponents from scoring).
		A PWP higher than winning percentage by a lot indicates an "underperforming" team, and one lower by a lot a team that has won a number of close games (a "lucky" team).

		In that essay, we arrive at a winning percentage for goaltenders that is (for the most part) attributable only to the goaltender, not to the team he plays for.
		Now, using the winning percentages for each number of goals and the number of times each team scores each number of goals, we can calculate a weighted-average winning percentage.
		Winning is not linear; the results of above-average goaltending, offence, and defence is greater that the sum of the individual parts.

	Some New Statistical Calculations
		I don't disagree with measuring a team down the stretch, but if that is to be done and the RPI is superior to winning percentage over an entire season, it must be superior over the last 20 games too.
		In this method, opponents' winning percentage and opponents' opponents' winning percentage are taken over the whole season, with only the opponents of the last 20 games factored into the L20RPI.
		Method 2 - Only a 20 game sample is taken for each team, and opponents' winning percentage and opponents' opponents' winning percentage is taken only for that sample for each team.

	Adjusted Winning Percentage (Site not responding. Last check: 2007-11-04)
		To calculate a winning percentage, we take the points earned (6) and divide it by the number of games played times two (5*2 = 10).
		Similarly, you may earn two points for an overtime win, but you do not deserve a 1.000 winning percentage because you let your opponent have a point.
		Regulation wins are worth 2 points, overtime wins are worth 1 1/3 points, ties are worth 1 point, overtime losses are worth 2/3 point and regulation losses are worth 0 points.

	Factors Associated with Success Among NBA Teams
		Because the teams which advance to the playoffs are those that have the highest winning percentages in their respective divisions during the regular season, knowledge of factors which predict success during this period would be of educational value for NBA coaches and analysts.
		Additionally, every 1 percentage increase in the three-point conversion rate of the opposing teams is associated with a 4.24% decrease in winning percentage (95% confidence interval is 2.49% to 5.99%).
		Nevertheless, the fact that three-point conversion percentage also made a contribution to the regression model, albeit a smaller one, suggests the importance of teams forcing the opposition to hurry their three-point shots and to take these shots from non-optimal parts of the basketball court.

		Adjusting for park and era, Garvey's.459 Dodger slugging percentage is about even with Hodges'.488, but Gil's.360 OBP is a lot better than Garvey's.337 mark.
		They are virtually even in terms of Offensive Winning Percentage: Lee Sinins' Sabermetric Encyclopedia has them at.593 for Garvey,.583 for Hodges, and other forms of the Runs Created formula might have Hodges in front.
		In Win Shares, Bill James rates Garvey an A and Hodges a B as defensive players, but 1) defensive stats for first basemen are quirky, and 2) Hodges' defensive reputation was sensational.

	Ivars Peterson's MathTrek
		Teams are generally ranked on the basis of both winning percentage and "games behind" the leader.
		Once in a while, however, the team with the higher winning percentage may be at least one-half a game behind in the standings.
		He adds that if Team 2 has a winning percentage of exactly.500, the inconsistency can't arise because Team 1 could only be at least half a game behind Team 2 if its winning percentage was less than.500.

		win picks advertises their winning percentage as 57% last year.
		Because the winning percentage is based on the formula in use, and because of the very nature of handicapping and gambling, we obviously can't promise or guarantee that you'll win money with WinPicks.
		However, we can say that based on the feedback we get from our customers, we know that many WinPicks users have a winning percentage in the 55 to 60% range, and most do better than the 52.4% required to break even at most sportsbooks.

		She equated a winning percentage of less than 50 percent as random action and equated random action to unprofitable.
		So while the winning percentage for an option seller is very high, the average loser is much larger than the average winner for an option seller, usually resulting in catastrophic losses.
		This often is referred to as the “odds in their favor” or the “house edge.” A gambler may win on one roll of the dice, but over the course of a few hours or if the gambler stays at it long enough, the casino will always win because it relies on positive expectancy.

		The WPI (Winning Percentage Index) is a measure of strength of schedule and how a team does against that schedule.
		It is similar to the calculation of the RPI (Ratings Percentage Index) which is used by the NCAA as one of their factors in deciding which teams to invite to the NCAA tournament and where to seed them.
		The basic formula is 33% team winning percentage, 33% opponents' average winning percentage, and 33% opponents' opponents' average winning percentage.

		She has charged your group with determining which of the following players would help the most in improving the winning percentage: a home run hitter, a high-average hitter, a hitter who bats in more runs, a base stealer, or a pitcher with a low earned-run-average.
		In this webquest, you will examine the relationship of each of these statistics with the winning percentage to determine which other statistic is most closely related to it.
		You will also want to obtain the regression equation where winning percentage is the y or dependent variable, and the other variable is the x or independent variable.

	Winning Percentages gambling sports betting handicapping sportsbetting wagering football handicappers hockey basketball ...
		The fact is, the difference between the percentage of bets won by successful sports bettors and the percentage of bets won by chronic losers is relatively very small.
		The measure of success of a sports handicapper is not his percentage of winning bets, but the relative amount of profit he made over any given period of time.
		When risking 11 to win 10 it is best to use no more than 2% of your bankroll per bet - (Most pros use about 1 percent) - and 'pull the trigger' whenever you feel you have at least a 55% expectation of winning.

	UPF - Hand winning percentage? (Site not responding. Last check: 2007-11-04)
		You don't have to win 10% of your hands, although theoretically speaking that would be about right.
		So if that was true, you would have to win about 1/3 of the flops you saw to average a 10% win rate.
		If you are at a tight table where you can steal pots and pick up the blinds often then yes maybe 13% would lead to a winning game but if you are at a game where people are capping it pre flop every hand the same 13% figure will lead to you going broke.

	MONEY MANAGEMENT (Site not responding. Last check: 2007-11-04)
		Some "pros" try to combine the opposing theories by advising that a set percentage of a starting bankroll be wagered on games until the total funds are increased or decreased to a degree (50%, for example), at which point the percent is recalculated from the new bankroll amount.
		Since percentage wagering is clearly superior to flat betting it is most financially favorable to reconcile the fixed percentage of bankroll before each wager to avoid the mistaken use of a flat betting scheme for any number of games.
		A winning percentage of 52.5% or less will not show a profit regardless of how small the bankroll percent wagered is, so we find that there is no overall advantage of risking just 1% on every game.

	Streamlining the "Pythagorean Theorem of baseball" - Inside Science News Service
		Introduced in the 1980s, the "theorem" predicts the winning percentage of a baseball team based on how many runs the team scores--and how many runs it allows.
		Fans compare the Pythagorean Theorem to the actual winning percentage, in an effort to determine if a team is under- or over-achieving.
		To predict the winning percentage of a team, one new model simply uses a little addition, subtraction, and multiplication.

	The Ratings Percentage Index Myth
		Comparing only the won-loss percentage of the last place team of a power conference with the won-loss percentage of a low-level conference champion, with no regard for the schedule each school actually played, one would be completely misled as to which team was the stronger.
		You could imagine this as the 25% of the rating, which is based on the team's winning percentage, as being attenuated (corrected) by the 50% of the rating which is based on the opponent's record.
		So that, for example, if a team has won all their games, but it has come against opponents with terrible records, the team's high 25% portion of the RPI will be decreased by the 50% of the opponent's record to reflect that the 25% may not be an accurate gauge of its actual strength.

		The conference's.958 winning percentage is far ahead of the Pacific-10 Conference's.731 and the Atlantic Coast Conference's.722.
		The highest nonconference winning percentage in the 1980s was posted by the Pac-10 in 1988, when it compiled a.794 (27-7) winning percentage.
		This high winning percentage and the wide variation in the number of such games among conferences are the reasons these games are deleted when comparing the I-A conferences.
