Often people who are not familiar with the nature and limitations of statistical methods tend to expect too much of the rating system. Ratings provide merely a comparison of performances, no more and no less. The measurement of the performance of an individual is always made relative to the performance of his competitors and both the performance of the player and of his opponents are subject to much the same random fluctuations. The measurement of the rating of an individual might well be compared with the measurement of the position of a cork bobbing up and down on the surface of agitated water with a yard stick tied to a rope and which is swaying in the wind.

In theory, there is no difference between theory and practice; In practice, there is.

Standings
- Includes links to consolidated conference and team Schedules & Results Where a ranking is indicated for a team, it is the better of the AP and Coaches' Poll rankings. Games are highlighed if the sum of the team rankings is 50 or less (top 25s, top 10 vs top 40, etc).
- Interconference Records
- The individual conference pairings are listed with the average relative strength of the opponents.
- Scoring Stats
- Scoring offense normalized by SOS(opponents' scoring defense) and scoring defense normalized by SOS(opponents' scoring offense). In the report mPF is measured Points For, mPA, measured Points Allowed, and PF/PA are the normalized values. mPF and PA will not match the NCAA stats, because the data only includes D1A opponents.
- Common Opponents
- Lists all team pairs that have a common opponent, indexed by team name. Indicates number of wins by each member of the team-pair against the common opponents, and links to schedules for each team.
- College Football Rankings comparison
