ryumast3r Ballot for 2021 Week 15 & Bowls

Ballot Type: Computer

Submitted: Dec. 5, 2021, 5:19 p.m.

Overall Rationale: How it works: This is the
Biorhythmic Ratings Over Holistic Methodology (BROHM) rankings
originally created by /u/factorialite and modified and used with their
permission. The way BROHM works is that each team is assigned points
based on the following: P5 teams 150 points to
start; G5 teams 100 points; FCS Playoff (last year) teams 75 points; and
all
other FCS teams 50 points. For each game, a team contributes half
of its points
into the game pool (so if a P5 team starts against another P5 team they
each contribute 75 points). Then, they take out points based on their
Pythagorean share in that game
(PointsFOR^2/(PointsFOR^2+PointsAGAINST^2)). This way, it's possible for
a "bad" team to play a "good" team close and ultimately win points
despite losing the game. Alternatively, it is possible for a "good" team
to win a game and ultimately lose points to a "bad" team by not beating
them by enough. Lastly, to help prevent as major swings every week while
also filtering generally "good" teams to the top, this ranking is run
through several times. I found this helps stabilize the rankings
week-to-week, however it doesn't prevent the model from coming up with
extremely "hot" takes (which add to the fun, imo).
