The model makes S. Costoulas the favorite with a 54% win probability, against T. Prozorova's 46% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.87; the offered odds are around @2.31 (a 43% implied), slightly above the market, so the model is a touch more optimistic.
Several factors explain the number: #152 vs #180 (better ranked); model 54% vs market 43% → 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 54%, 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 46 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.
