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

Humidity
19%

Very dry air: the ball travels faster.

Wind
16 km/h

Light wind: no noticeable effect.

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 · ELO ESTIMATE

The model makes F. Diaz Acosta the favorite with a 60% win probability, against J. Munar's 40% — a solid favorite, though Munar keeps real chances. Converted to odds, that probability is worth about @1.66; the offered odds are around @1.83 (a 55% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: 1960 vs 1888 — favorite by rating; challenger tier · 317 matches in the favorite's track record; these are softer, less-analyzed markets.

Read it with caution. This number does NOT come from the ATP factor model, but from the tour's real Elo: it ranks who is the favorite well, but it is a coarser estimate. Being the favorite is not being the winner: roughly 40 out of every 100 times Munar wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity. Watch out for: Soft market: the value edge in Challenger/ITF is NOT proven live — treat it as an estimate, not an opportunity..
