Consistent bounce, medium-fast: neutral conditions, no style favored.
Warm: the ball flies a little more and fitness counts.
Dry air: the ball travels normally.
Light wind: no noticeable effect.

The model makes M. Arnaldi the favorite with a 59% win probability, against B. Tomic's 41% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.69; the offered odds are around @1.46 (a 68% implied), slightly below the market, so the model is a touch more cautious.
Several factors explain the number: #38 vs #185 (better ranked); model 59% vs market 68% → the model sees it as less likely than the odds; 4/10 in recent matches.
Read it with perspective. Our probability is calibrated — when the model says 59%, 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 41 out of every 100 times Tomic 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.
