BREAKDOWN · ELO ESTIMATE

The model makes A. Weis the favorite with a 53% win probability, against N. Mashtakov's 47% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.89; the offered odds are around @1.79 (a 56% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: 1713 vs 1693 — favorite by rating; challenger tier · 377 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 47 out of every 100 times Mashtakov wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
