The most extreme case was in the National League in 1970 when Chicago won the Pythagorean pennant by 3 games over Cincinnati, but Cincinnati actually won 18 more games than Chicago did, a net change of 21 games.

Remember to take this information for what its worth. I do not necessarily look at myself as being a so called sharp sports bettor. It would be expected that differences in performance in games decided by more than one run also could account for some of the differences noted between actual and Pythagorean records. Much of this randomness comes from inconsistent officiating, injuries, and pure luck itself. For example, as R/OR increases from 1.0 to 1.1, predicted WP increases from .500 to .543, or by .043; and as R/OR increases from 1.7 to 1.8, predicted WP increases from .725 to .746, or by .021. One of his largest contributions was the Pythagorean Theorem of Baseball. Think of points scored as (a), and points allowed as (b) where (c) is a function of the (a and b) linear equation and we just want to know what the relationship is between a^2/c^2 (c^2 is a^2 + b^2)to get a percentage of wins multiplied by the total games. The corresponding figure for the 50 seasons of play in the 1969 to 1993 period, with one round of playoffs to determine pennant winners, was 38 percent.

It should be noted that with postseason playoffs starting in 1969, the actual pennant winner may have been outclassed in both its actual and Pythagorean won-lost records. As of 2013, there is still little public awareness in the sabermetric community that a simple "teams win in proportion to quality" model, using the runs ratio as the quality measure, leads directly to James's original Pythagorean formula.

Miami Marlins: 77.5. In each of these two phases, a team can under-perform, perform as predicted, or over- perform.

Miami finished with 67 wins, four short of their preseason win total. Once again, by looking at these numbers it can be concluded that the skill of the pitcher and how he uses his pitches is more valuable to the team than a teams average velocity and pitch type percentage thrown.
