BREAKDOWN · MODEL ANALYSIS

The model makes K. Volynets the favorite with a 66% win probability, against S. Stephens's 34% — a solid favorite, though Stephens keeps real chances. Converted to odds, that probability is worth about @1.53; the offered odds are around @1.35 (a 74% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #102 vs #363 (better ranked); model 66% vs market 74% → the model sees it as less likely than the odds; 7/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 66%, that outcome happens roughly that percentage of the time, with ~64% out-of-sample accuracy — but being the favorite is not being the winner: roughly 34 out of every 100 times Stephens 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.
