BREAKDOWN · ELO ESTIMATE

The model makes E. Ribeiro the favorite with a 53% win probability, against N. McDonald's 47% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.89; the offered odds are around @2.38 (a 42% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: 1656 vs 1636 — favorite by rating; challenger tier · 248 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 McDonald wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
