For example, the 2008 New Orleans Saints went 88 despite 9.5 Pythagorean wins, hinting at the improvement that came with the following year's championship season. The fact that the most accurate exponent for baseball Pythagorean formulas is a variable that is dependent on the total runs per game is also explainable by the role of chance, since the more total runs scored, the less likely it is that the result will be due to chance, rather than to the higher quality of the winning team having been manifested during the scoring opportunities.

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). A z-score of 1.13 corresponds to a 74 percent chance. The SPORTS REFERENCE and STATHEAD trademarks are owned exclusively by Sports Reference LLC. The won-lost records in one-run games were nearly identical for Minnesota (2422) and Toronto (2724).
