Rick's Ratings
My D1 basketball ratings are available in PDF or plain text form. Three different ratings are calculated. They all use the same basic algorithm: a team's rating is based on its game results adjusted for the strength of its opposition.
In the "linear" version, each D1 team is initially assigned a rating equal to its average score differential versus other D1 teams. Then each team's strength of schedule is calculated as the average rating of all its opponents, and its rating is recalculated as its score differential plus 99.999% of its strength of schedule. This strength-of-schedule adjustment is repeated until no team's rating changes by more than a tiny fraction of a point.

In the "flat" or score-blind version, the actual score is not considered. A win is worth 1, a loss is worth -1, and your initial rating is the average of your wins and losses. So a team with a 2-1 record would have an initial rating of (1+1-1 )/3, or one third.

In the hybrid version, score differential is considered up to a point; however, instead of a linear scale, a logarithmic scale is used. A blowout is more significant than a squeaker, but a thirty-point win is not worth much more than a 20-point win.
