ExternalTangents Ballot for 2021 Week 8

Ballot Type: Computer

Submitted: Oct. 18, 2021, 12:40 p.m.

Overall Rationale: This is a predictive ranking system. No information outside of the current season is used. Only scores of games and home/away locations are used. Losses against FCS opponents are counted, wins are not. It starts all calculations fresh each week from 0 and then iterates until ratings stabilize, so past weeks' results are reevaluated from the perspective of the current week. Numerical scores for each team represent how many points above or below average they are. Subtract scores to get an estimated spread between two teams, with 3 points given to the home team. Preseason rankings are included for stability and wear off over the season. At this point in the season, the ratings are starting to gain a measure of accuracy.
