Since the hypothesis holds that systems equilibrate through time by decelerating decrease in variation, we might predict that, from 1901 to 1930, when the American League was new but the National already in middle age, variation in American League records should decrease more rapidly than comparable measures in the National League. This pattern does indeed emerge, both for standard deviations of batting averages in my calculations, and for the history of differences in best versus worst teams in the data of Chatterjee and Yilmaz.
