BREAKDOWN · ELO ESTIMATE

The model makes H. Dellien the favorite with a 68% win probability, against F. Ferreira Silva's 32% — a solid favorite, though Silva keeps real chances. Converted to odds, that probability is worth about @1.47; the offered odds are around @1.46 (a 68% implied), virtually the same as what the market prices in.

Several factors explain the number: 1854 vs 1721 — favorite by rating; challenger tier · 375 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 32 out of every 100 times Silva wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
