BREAKDOWN · ELO ESTIMATE

The model makes S. Gulin the favorite with a 63% win probability, against F. Arnaboldi's 37% — a solid favorite, though Arnaboldi keeps real chances. Converted to odds, that probability is worth about @1.59; the offered odds are around @1.50 (a 67% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: 1746 vs 1653 — favorite by rating; challenger tier · 261 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 37 out of every 100 times Arnaboldi wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
