BREAKDOWN · MODEL ANALYSIS

The model makes T. Kostovic the favorite with a 56% win probability, against D. Semenistaja's 44% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.79; the offered odds are around @1.66 (a 60% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #186 vs #120; 7/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 56%, 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 44 out of every 100 times Semenistaja 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.
