CONDITIONS OF THE MATCHin the modelcontext
Surface
Hard

Consistent bounce, medium-fast: neutral conditions, no style favored.

Temperature
35°C

Strong heat: warm air speeds the ball up and physical wear tells in long matches.

Humidity
31%

Very dry air: the ball travels faster.

Wind
19 km/h

Some wind: makes baseline control harder.

Altitude
540 m

Moderate altitude: the ball flies a little more than at sea level.

Surface feeds the model (surface specialization is one of its factors). Weather and altitude are context we publish for you — they do NOT move the probability.

BREAKDOWN · MODEL ANALYSIS

The model makes E. Mertens the favorite with a 55% win probability, against N. Bartunkova's 45% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.81; the offered odds are around @1.65 (a 61% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #24 vs #38 (better ranked); 1-1 even; 60% career on the surface; model 55% vs market 61% → the model sees it as less likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 55%, 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 45 out of every 100 times Bartunkova 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.
