Parry's Power Guide to high school football

Each week throughout the prep football season, the Deseret News prints Parry's Power Guide. So what exactly is Parry's Power Guide? Is it like the BCS of high school football? Sort of.

Noland Parry, a resident of Pleasant Grove, created the computer ranking system in 1979.

The guide's purpose is to compare teams based on an offensive and defensive rating. The offensive rating is generated by final scores, and the defensive rating is based on strength of schedule. When combined together, according to the guide, the difference in two teams' ratings is the expected point spread if those teams meet.

The ratings are updated weekly by the computer, which consistently predicts 75 percent of the winners correctly.
