Thanks for taking the time to crunch these numbers =D>

I don't know how you come up with the results (I bet it is not quick and easy) but they are very interesting.

Algorithm is explained here:

http://www.laxpower.com/update10/ex_pr.php

The laxpower people were nice enough to provide enough details on how they compute their power rating so I took that writeup and emulated for our NCJLA teams. I omit a few details (like home field advantage), but I think I've captured the main part of the algorithm.

pick - how does the formula take into account games where an "A" team is playing a "B1" team?

The power ratings have no concepts of A, B1, or B2 teams. It only considers scores between games.
