The fact that accurate formulas for variable exponents yield larger exponents as the total runs per game increases is thus in agreement with an understanding of the role that chance plays in sports. The way I analyze baseball is to utilize the metrics and the statistics to try and find betting opportunities. The empirical failure of his attempt led to his eventual, more circuitous (and ingenious) and successful approach to log5, which still used quality considerations, though without a full appreciation of the ultimate simplicity of the model and of its more general applicability and true structural similarity to his Pythagorean formula. But this is a two-stage process. Some defensive statistics Copyright Sports Info Solutions, 2010-2023.

The latter is more the case in basketball, for various reasons, including that many more points are scored than in baseball (giving the team with higher quality more opportunities to demonstrate that quality, with correspondingly fewer opportunities for chance or luck to allow the lower-quality team to win.).

The initial formula for pythagorean winning percentage was as follows: (runs scored ^ 2) / [(runs scored ^ 2) + (runs allowed ^ 2)] That formula proved more predictive than basic winning percentage when trying to predict a team's future performance, although in the years since pythagorean winning percentage was popularized, other analysts have attempted to find an even more accurate formula. And lastly, the introduction of division play in 1969, with postseason playoffs to determine pennant winners, has decreased greatly the probability of the Pythagorean pennant winner being the actual pennant winner. The won-lost records in one-run games were nearly identical for Minnesota (2422) and Toronto (2724). In 2003, Hein Hundal provided an inexact derivation of the formula and showed that the Pythagorean exponent was approximately 2/() where was the standard deviation of runs scored by all teams divided by the average number of runs scored. Is it possible for an NFL team to score more points than they give up and have a losing record? ", In 2013, statistician Kevin Dayaratna and mathematician Steven J. Miller provided theoretical justification for applying the Pythagorean Expectation to ice hockey.

The formula has also been used in the National Football League by football stat website and publisher Football Outsiders, where it is known as Pythagorean projection. [James did not seem aware at the time that his quality measure was expressible in terms of the wins ratio. The Pythagorean pennant winners for those six years present a different picture: Cleveland (1926), New York (1927), Philadelphia (1928 and 1929), Washington (1930), and New York again (1931).

It is my guess that it would still be the case that only a small proportion of the seasons with different actual and Pythagorean pennant winners would differ by one standard deviation or more in their records and that seasons with differences of two standard deviations or more would be extremely rare (perhaps just the 1987 American League). Slider and curveball percentages actually had a 0.000 p-value, meaning they contributed literally nothing towards wins.
