This site provides general information about the AQB ratings system and the ratings function. The AQB Active, QualityBased Rating System uses historical data to assign relative performance ratings to each team in the chosen sport. The base for the rating system is the first game in that sport, and ratings begin from that date. Ratings are recalculated after every game using the ratings function, and the new ratings are used for that teams next game.
