JJ Aldrich vs Regina Tarin
Sat, Sep 12, 2:00 PM ET · W Flyweight · 3 rounds · Noche UFC: Silva vs. Delgado · Desert Diamond Arena
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.
Who the model expects to win
Probabilities over the two fighters, from the head that was evaluated on its own preregistered bar.
JJ Aldrich15-7-0
Regina Tarin8-0-0Regina Tarin wins 100% of tracked bouts to Aldrich's 65%, the shorter record is Tarin's (1 vs 17), so the read leans on the opponent's history — and the matchup profiles as one that reaches the judges.
How it ends
Read among fights that end with a winner — a draw or no-contest sits outside this sample, so the three add to 100%.
How far it goes
R3+ carries every fight that reaches the judges as well as every round-3-or-later finish.
“Goes the distance” is the method head’s decision probability, not a separate model — so it cannot disagree with the bar above it.
What the corpus knows about each of them
Tracked bouts only — a fight outside the corpus is not counted, and a thin record says so.
4-1 in the last 5. 9% of wins come by finish; 82% of fights reach the judges.
1-0 in the last 1. 0% of wins come by finish; 100% of fights reach the judges.
Where these numbers come from
Three separate heads — winner, method and round — each fitted on a corpus of tracked UFC fights and each published only on its own PASS verdict against a bar frozen before it was fitted. This is the one model on the site that beat its baseline on every head it was tested on.
