BREAKDOWN · ELO ESTIMATE

The model makes A. Andrade the favorite with a 53% win probability, against M. Rottgering's 47% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.90; the offered odds are around @2.32 (a 43% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: 1802 vs 1783 — favorite by rating; challenger tier · 280 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 Rottgering wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
