How it works This FBS-specific model blends 345 current-season games with 956 games from 1927, 1926, 1925. Current-season influence is 100% for the rating relationship, 26% for home-field advantage, and 41% for the error range. Before week-eight recalibration, probabilities are limited to 5–95% to reflect early-season uncertainty.
