Part 1 of our Rankings Tutorial: Introduction
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.
