BREAKDOWN · MODEL ANALYSIS

The model makes C. Liu the favorite with a 60% win probability, against M. Stoiana's 40% — a solid favorite, though Stoiana keeps real chances. Converted to odds, that probability is worth about @1.67; the offered odds are around @1.80 (a 56% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: #96 vs #116 (better ranked); performs +9% above baseline (48% career on the surface); 6/10 in recent matches; 5 wins in a row.

Read it with perspective. Our probability is calibrated — when the model says 60%, 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 40 out of every 100 times Stoiana 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.
