Efficiency Data Correlations
Updated January 30, 2023
Some efficiency data ratings are more strongly correlated to winning and losing than others. The table below outlines the relationships between end of year ratings with same season (retrodictive) performance and next season performance. W% represents the winning percentage in head to head matchups of teams with stronger ratings than their opponents. CW represents the correlation of team ratings to winning percentage against FBS opponents. CM represents the correlation of the ratings delta between teams in head to head matchups with the scoring margin result of those matchups. CR represents the correlation of the rating with the same rating the following year.
