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 same relationship is true for any number of runs scored and allowed, as can be seen by writing the "quality" probability as [50/40] / [ 50/40+40/50], and clearing fractions.

Calculations of Pythagorean won-lost records were rounded to whole numbers of wins and losses (reflecting the fact that actual won-lost records do not have fractions), and thus there are a few cases with ties for the Pythagorean pennant winner. From 1969 to 1993, with two divisions per league (East and West), there was one tier of playoffs to determine pennant winners.
