In 1951 racing historian Russ Catlin officially revised AAA records with championship results based on all AAA races from 1902-1915 and 1916-1919. This had the effect of retroactively creating seven newly credited champions and changing the 1909 champion from Bert Dingley to George Robertson and the 1920 champion from Gaston Chevrolet to Tommy Milton.

Although the 1909-1919 races were not considered to be part of a championship at the time, they are included in statistics by most historians.
