BREAKDOWN · MODEL ANALYSIS

The model makes C. Liu the favorite with a 57% win probability, against M. Stoiana's 43% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.75; the offered odds are around @1.76 (a 57% implied), virtually the same as what the market prices in.

Several factors explain the number: #96 vs #116 (better ranked); performs +9% above baseline (48% career on the surface); 7/10 in recent matches; 5 wins in a row.

Read it with perspective. Our probability is calibrated — when the model says 57%, 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 43 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. This is informational analysis, not a betting recommendation. 18+ · play responsibly.
