These ratings were devised by Joe Stanford, a 1990 graduate of Indiana University. They were developed as a hobby and inspired by systems such as The Dunkel Index and Jeff Sagarin’s Sports Ratings.
Special thanks to Fort Wayne (Indiana) News-Sentinel sportswriter Blake Sebring for his encouragement, and for posting the ECHL (East Coast Hockey League) Ratings in his blog “Tailing the Komets” for the fifth consecutive season. Thanks also to Kenneth Massey, who provided his computer rankings for the Bowl Championship Series, for posting the NCAA Football and NCAA Basketball Ratings in his Ranking Composite websites.

EXPLANATION OF THE RATINGS
The Stanford System uses a series of algorithms to connect and compare sports teams within their leagues based solely on the results of games. There are no “starting ratings” or any other subjective factors.
The teams are ranked in order of their Power Rating, which is a measure of each team’s relative strength. Immediately to the right, each team’s Power Rating and Rank prior to the current week of games is shown.
The Schedule Rating and Rank is a measure of the strength of each team’s previous opponents, and takes into account whether the games were at home or on the road. Games scheduled but not yet played are not included in this rating.
These ratings include a Home edge. Since the factor is based on game results, it will change slightly each week. To predict the outcome of an upcoming game, compare the two teams’ Power Rating after adding the indicated Home edge to the home team. If the game is to be played at a neutral site, ignore the Home edge in the comparison.
The Retrodictive Rating does not consider margin of victory, but does take into account whether the games were at home or on the road. It measures what each team has already accomplished. The Retrodictive Rating is not intended to predict the outcome of upcoming games.
The Power Rating, on the other hand, includes a factor for margin of victory, and is an excellent predictor of upcoming games.
