__RATINGS: by Ned Freeman__

*only*, how good the team appears to be entering the season (based on players graduated/back) is a factor in the ratings early in the year in order to improve early-season accuracy of the ratings, but this is eliminated as the season goes on. For more information on this, please click here

*is*used as a factor. It is much easier to explain that way. When margins are used, the differences in ratings between two teams is roughly a measure of how many

*points*better one team is than another. An 80 should beat a 60 by 20, etc.

Example:

Team A's rating is 10.

Team B's rating is 0.

Team C's rating is -5.

Team D's rating is -8.

Team E's rating is -10.

Points aren't everything by any means- the win or the loss is always the most important thing, even when margins are used. There is a "diminishing returns" principle at play so as to not fully credit a team for blowing out a weak opponent. In addition to the cutoff point past which margins are not counted, there is a "win minimum" as well a maximum-- a number which no win is credited as being below...because, of course, a one point win isn't just barely better than a one point loss. Far from it.) All teams are adjusted similarly, and then we start over from the beginning with the new ratings- A is now an 8 and expected to perform accordingly, etc. This is done repeatedly until their is no longer any movement in the ratings, and they settle in where they "should" be.

*this*way was hard!)- that's why we started the example off with the teams already having ratings.
