Inter-division results
Home, road, and neutral scoring averages for games between teams from different divisions. Division 1 is considered to consist of three "divisions" - "BCS" includes all the teams in Football Bowl Subdivision conferences whose champion is an Automatic Qualifier, "nBCS" are the teams in the Football Bowl Subdivision who aren't in AQ conferences, and "1AA" are the teams in the Football Championship Subdivision. "D2", "D3" and "NAIA" are self-explanatory.

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.
