How it works This FBS-specific model blends 209 current-season games with 398 games from 1907, 1906. Current-season influence is 100% for the rating relationship, 17% for home-field advantage, and 29% for the error range. Before week-eight recalibration, probabilities are limited to 5–95% to reflect early-season uncertainty.
