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 33.15%.
For the current season, the ratings accurately account for the winner of 623 of 648 total games including 0 tie(s) (96.14%) and accurately reflect approximately 68.3% of all game margins within 13.26 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.

Therefore the Competitive Rating is the rating required to go undefeated in a round robin tournament among region teams 20% of the time. This rating favors regions with larger numbers of highly rated teams. The “Average Rating” is the rating required to win 50% of all games against the region’s teams in an infinite round robin competition.
