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. While still good, this is noticeably worse than their actual win percentage of .621. In other words, this is the league's runs scored per nine innings times 1.5, plus three.
