Featherweight, 3 rounds on UFC 331: Van vs. Pantoja 2. The model read both fighters' histories.

model ufc-fight-model@e657fc40b64dno run count recordedproduced Sep 17, 11:22 AM ET

How much history is behind this. One fighter has no UFC history in our corpus, so this read leans on the established fighter's record and league-average priors for the newcomer. Treat it as weaker than a bout where both sides are known.

“Goes the distance” is the method head’s decision probability, not a separate model — so it cannot disagree with the bar above it.
