Ratings Points Explained

My points system is not complex.  I am giving it a 'tryout' for this season to see how well it does.  I am not a mathematician or a statistics guru.  I just came up with it after looking at a few different rating systems.

This system IS NOT what the SDHSAA uses to determine their seedings.

Here is how you figure out mine:

Points for a win:
50 pts: win against a 11AA team
45 pts: 11A
40 pts: 11B

Points for a loss:
30 pts: loss against a 11AA team
25 pts: 11A
20 pts: 11B

Bonus Points:
1 pt: win by 8-14 points
2 pts: by 15-21 points
3 pts: by 22-28 points
4 pts: by 29-35 points
5 pts: by 36-42 points
6 pts: by 43-49 points
7 pts: by 50-56 points
8 pts: by 57-63 points
9 pts: by 64-70 points 

Negative Points:
-1 pt: loss by 8-14 points
-2 pts: by 15-21 points
-3 pts: by 22-28 points
-4 pts: by 29-35 points
-5 pts: by 36-42 points
-6 pts: by 43-49 points
-7 pts: by 50-56 points
-8 pts: by 57-63 points
-9 pts: by 64-70 points

Opponent wins (strength of schedule):
3 bonus points are given to a team for every win their opponents get during the season.  The more 'B' a team has means their scheduled opponents are winning and, in turn, should mean a stronger schedule. 

Example:
In week one, Sioux Falls Lincoln, a Class 11AA team, defeated Rapid City Stevens, also a 11AA team, 64-0.

Sioux Falls Lincoln earned the following points:
50 points - win versus a 11AA team
9 points - won by 38 points
59 total points for Sioux Falls Lincoln in week one

Bonus:
After Week 6, Sioux Falls Lincoln has acquired 96 bonus points thanks to their opponents on their schedule having won a total of 32 games (32 x 3).

I know that people will have problems with the strength of schedule element and the bonus points for margin of victory but it is a system that I am going to run with for this year.  I'll monitor it.  If it needs tweaking next year, then I will do it then.  Thanks!
