›Model 78% vs market 67% → the model sees it as MORE likely than the odds
The model makes A. Potapova the favorite with a 78% win probability, against S. Stephens's 22% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.29; the offered odds are around @1.49 (a 67% implied), slightly above the market, so the model is a touch more optimistic.
Several factors explain the number: #25 vs #240 (better ranked); 6/10 in recent matches; 1-0 in favor; model 78% vs market 67% → the model sees it as more likely than the odds.
Read it with perspective. Our probability is calibrated — when the model says 78%, 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 22 out of every 100 times Stephens 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.
