"Fair" is the model's no-vig price for that exact outcome; "book" is the best live sportsbook price for it (hover for the book). A green book price is longer than fair — value if you trust the model. Method prices update with each odds sync.
The model makes Perez a solid 66% favorite. Expect Perez to chase the takedown (4.4/15 min at 49%) while Dumont tries to keep it standing behind 67% takedown defense. Dumont tends to settle in for the long haul — 11 of 12 tracked fights reached the judges. Perez's most likely path is on the scorecards (50%), and the fight goes the distance 78% of the time.
Model: recent-fight output & defense rates (ESPN box stats), career method splits, durability, layoffs, and physical edges through a bounded logistic; weights tuned by walk-forward backtest on 1,500+ UFC fights — 61% winner accuracy and 32% exact winner-plus-method on 204 held-out fights (vs 26% picking favorite-by-decision). Probabilities are discounted in boom-or-bust matchups (both fighters' bouts ending fast) and squeezed toward the betting market's implied odds where a line exists — divergence beyond 10 points counts half. Experimental — size responsibly.
