Bill James realized this long ago when noting that an improvement in accuracy on his original Pythagorean formula with exponent two could be realized by simply adding some constant number to the numerator, and twice the constant to the denominator. An ex- ample of the latter is provided by the 1987 American League season discussed above. Two standard deviations correspond to 12.72 wins. Furthermore, "[t]he Pythagorean projection is also still a valuable predictor of year-to-year improvement. Baseball-Reference.com, for instance, uses 1.83 as its exponent of choice .

Rounding two standard deviations to the nearest whole number (13) means that an average teams record would range from about 6894 to about 9468 about 95 percent of the time (reflecting the proportion of the area under a bell-shaped curve within two standard deviations of the mean). The SPORTS REFERENCE and STATHEAD trademarks are owned exclusively by Sports Reference LLC. 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). This is because a season (with only 162 games) does not provide a large enough sample size to conclude that a team is the best team in its league unless it wins 18 or more games than any of its opponents.

Full-year historical Major League statistics provided by Pete Palmer and Gary Gillette of Hidden Game Sports. Run differential, the simplified version of the Pythagorean Theorem of Baseball, breaks the formula down to one statistic. By plugging these expected runs scored and allowed into the pythagorean formula, one can generate second-order wins, the number of wins a team deserves based on the number of runs they should have scored and allowed given their component offensive and defensive statistics. Various candidates for that constant can be tried to see what gives a "best fit" to real life data. FanGraphs' BaseRuns approach is even friendlier and suggests 26-27. .

The Pythagorean pennant winners are predicted with a model that starts with the teams numbers of runs scored and runs allowed, thus excluding the variation inherent in an actual baseball season. The purpose of this paper has been to provide a general comparison of actual pennant winners and Pythagorean pennant winners for the National and American Leagues from 1901 to 2020.
