BREAKDOWN · MODEL ANALYSIS

The model makes J. Fonseca the favorite with a 87% win probability, against C. O'Connell's 13% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.15; the offered odds are around @1.21 (a 83% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: 6/10 in recent matches; 3 matches in the last 2 weeks.

Read it with perspective. Our probability is calibrated — when the model says 87%, that outcome happens roughly that percentage of the time, with ~65% out-of-sample accuracy — but being the favorite is not being the winner: roughly 13 out of every 100 times O'Connell 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.
