BREAKDOWN · ELO ESTIMATE

The model makes D. Ostapenkov the favorite with a 72% win probability, against Y. Dzhavakian's 28% — a solid favorite, though Dzhavakian keeps real chances. Converted to odds, that probability is worth about @1.39; the offered odds are around @1.30 (a 77% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: 1673 vs 1511 — favorite by rating; challenger tier · 139 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 28 out of every 100 times Dzhavakian 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..
