Maxwell GHSA Football Ratings
As this season's games are played, the Maxwell Ratings will be based on a modified logistic regression of the current football season's results in combination with each team's historical performance. More recent games and games against similarly rated opponents carry more weight and the weight of each team's historical performance diminishes as the team's season progresses.
The current total weight of all team’s historical performance is 100.00%.
For the current season, the ratings accurately account for the winner of 0 of 0 total games including 0 tie(s) (--.--%) and accurately reflect approximately 68.3% of all game margins within --.-- points.
The ratings are scaled so that 100.00 is the rating required to win 91.5% of all games in an infinite round robin tournament against all teams in the highest classification. The schedule strength is the rating required to win 50% of all games in an infinite round robin tournament against a particular team's opponents.
