BREAKDOWN · MODEL ANALYSIS

The model makes E. Mertens the favorite with a 65% win probability, against M. Chwalinska's 35% — a solid favorite, though Chwalinska keeps real chances. Converted to odds, that probability is worth about @1.54; the offered odds are around @1.41 (a 71% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #19 vs #25 (better ranked); 0-1 against; 61% career on the surface; model 65% vs market 71% → the model sees it as less likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 65%, 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 35 out of every 100 times Chwalinska 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).
