Books price Harris at 48% to win (vig removed) — our model has value of +17.3% on HarrisEdge = our model's win probability minus the market's implied probability (after removing the sportsbook's margin). Positive = the model thinks this fighter wins more often than the odds suggest, so their price is the value side. Bigger gaps deserve more skepticism, not more money.
"Fair" is the model's no-vig price for that exact outcome — compare it to your book's method-of-victory market: a book price longer than fair is value if you trust the model. (Our odds feed doesn't carry method markets, so we can't auto-compare yet.)
Median sportsbook implied win probability (vig included) at each odds snapshot since we started tracking this fight. A rising line = money and respect moving toward that fighter.
The model makes Harris a solid 65% favorite, more confident than the market's 48%. Harris is most dangerous early — 2 of 5 tracked wins ended in the first round. Harris's most likely path is on the scorecards (26%), and the fight goes the distance 34% of the time — if it ends inside the distance, round 1 carries the most risk.
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 1,535 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.
