To my knowledge, these are the only published ratings which minimize WRRV (Weighted Retrodictive Ranking Violation). In college football, this metric is tracked by Paul Kislanko for each of the ratings comprising Dr. Kenneth Massey’s College Football Ranking Composite. A special thank you to Dr. Massey for including the ratings in his Composite, and Todd Beck for tracking the performance of the ratings in various sports at his ThePredictionTracker website. Below are links with further information about WRRV, which include commentary by Paul Kislanko, Kenneth Massey, and Eugene Potemkin. The ratings can be volatile the first few games of the season, particularly when a highly favored team loses.
