BREAKDOWN · ELO ESTIMATE

The model makes A. Andreev the favorite with a 61% win probability, against S. Purtseladze's 39% — a solid favorite, though Purtseladze keeps real chances. Converted to odds, that probability is worth about @1.63; the offered odds are around @1.27 (a 79% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: 1685 vs 1606 — favorite by rating; challenger tier · 266 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 39 out of every 100 times Purtseladze wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
