BREAKDOWN · MODEL ANALYSIS

The model makes S. Costoulas the favorite with a 53% win probability, against T. Prozorova's 47% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.89; the offered odds are around @2.28 (a 44% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: #150 vs #165 (better ranked); model 53% vs market 44% → the model sees it as more likely than the odds; 5/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 53%, 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 47 out of every 100 times Prozorova 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.
