WinPicks Reference Manual
Section 7.7. Schedule Difficulty
All members of the WinPicks family can rank all teams according to their schedule difficulty. The team with the most difficult schedule is ranked first, and the team with the easiest schedule is ranked last. To use this option, select SCHEDULE DIFFICULTY from the VIEW menu.
Schedule difficulty is computed by taking the average power ranking of each team's opponents. When you change formulas or change the database method, the schedule difficulty rankings will also change.
