 The system is designed to be both predictive and retrodictive in nature, although in practice it has proven to be more strongly predictive than retrodictive.The ARGH Power Ratings evaluate teams taking into account a team's wins and losses, its points scored both for and against, its schedule, and the location of the team's games.It is unusual in that for the purposes of providing meaningful ratings throughout the season it seeds teams based on several stated criteria, including records from the previous two seasons, the previous year's strength of schedule, the number of returning starters, whether the head coach is returning, whether the starting quarterback is returning, and published recruiting rankings from several preseason publications.
