Track your profit over a large enough sample size (say 250 wagers) of Positive EV bets and yo. Counter Strike Tips. Since the calculation of m in (5) above is not affected by the y, replacing b = 0.50 by either b = 0.5002 or b = 0.5001 in Equation 2 above will change the expected winning percentage y in the 4th decimal place. Whisnant's answer, based on a Markov chain analysis that simplifies and simulates an infinite number of baseball games while eliminating the random fluctuations found by analyzing actual data from a finite number of games: where a = 0.723 (RPG1 + RPG2)^.373 and b = 0.977 (RPG1 + RPG2)^( -.947).

A team strongly lagging Pythagorean expectation is seen through this filter as due for a win streak, while one strongly ahead of it is seen as due for a losing streak.In practice, Pythagorean win percentage has shown to be quite accurate usually being off by 2 3 wins over the course of a baseball season. And is slugging percentage (SLG, total bases divided by at bats) a good measure of that consistency? For the NFL, EXP (W%) = [(PS PA)W% / [650.36(PS PA)W% 39,803]]*(PS PA) + 0.50. For example, a win by a big underdog results in a bigger exchange of points than a win by a favorite and the larger the margin of victory, the larger the exchange.
