BREAKDOWN · MODEL ANALYSIS

The model makes Q. Halys the favorite with a 61% win probability, against F. Diaz Acosta's 39% — a solid favorite, though Acosta keeps real chances. Converted to odds, that probability is worth about @1.63; the offered odds are around @1.31 (a 76% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #52 vs #82 (better ranked); 0-1 against; model 61% vs market 76% → the model sees it as less likely than the odds; 8/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 61%, that outcome happens roughly that percentage of the time, with ~65% out-of-sample accuracy — but being the favorite is not being the winner: roughly 39 out of every 100 times Acosta wins. The model also tends to agree with the market, so the odds already capture almost all the edge: don't take it as a sure value. Watch out for: Unfavorable head-to-head record (0-1).
