BREAKDOWN · ELO ESTIMATE

The model makes J. Kumstat the favorite with a 77% win probability, against A. Wazny's 23% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.31; the offered odds are around @1.10 (a 91% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: 1745 vs 1539 — favorite by rating; challenger tier · 82 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 23 out of every 100 times Wazny 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..
