CONDITIONS OF THE MATCHin the modelcontext
Surface
Clay

Slow court, high bounce: longer points, rewards whoever holds up from the baseline.

Temperature
35°C

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

Humidity
20%

Very dry air: the ball travels faster.

Wind
9 km/h

Light wind: no noticeable effect.

Altitude
667 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 · ELO ESTIMATE

The model makes R. Nijboer the favorite with a 59% win probability, against A. Manzanera Pertusa's 41% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.69; the offered odds are around @1.40 (a 71% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: 1682 vs 1617 — favorite by rating; itf tier · 362 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 41 out of every 100 times Pertusa 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..
