BREAKDOWN · MODEL ANALYSIS

The model makes C. Alves the favorite with a 52% win probability, against S. Lamens's 48% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.92; the offered odds are around @5.45 (a 18% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: #296 vs #182; model 52% vs market 18% → the model sees it as more likely than the odds; 8/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 52%, 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 48 out of every 100 times Lamens 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.
