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.

WHAT THE ESTIMATE IS BASED ON

Tour Elo: 1845 vs 1822 — favorite by rating

ATP qualifying / early round · 226 matches in the favorite's track record

Elo estimate (not the ATP factor model): qualifying draws have no clean main-tour history

BREAKDOWN · ELO ESTIMATE

The model makes J.J. Wolf the favorite with a 53% win probability, against J. Duckworth's 47% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.88; the offered odds are around @1.58 (a 63% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: 1845 vs 1822 — favorite by rating; atp qualifying / early round · 226 matches in the favorite's track record; qualifying draws have no clean main-tour history.

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 47 out of every 100 times Duckworth 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: Qualifying/soft context: Elo estimate only — read the round context (already-through, lucky loser, dead rubber) from the dossier; it is not a proven edge..
