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

›Solid on Hard: 60% career on the surface
The model makes L. Tien the favorite with a 66% win probability, against D. Merida Aguilar's 34% — a solid favorite, though Aguilar keeps real chances. Converted to odds, that probability is worth about @1.51; the offered odds are around @1.44 (a 69% implied), slightly below the market, so the model is a touch more cautious.
Several factors explain the number: #19 vs #63 (better ranked); 6/10 in recent matches; 60% career on the surface.
Read it with perspective. Our probability is calibrated — when the model says 66%, 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 34 out of every 100 times Aguilar 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.
