BREAKDOWN · ELO ESTIMATE

The model makes J. Kumstat the favorite with a 57% win probability, against P. Brunclik's 43% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.77; the offered odds are around @1.64 (a 61% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: 1801 vs 1755 — favorite by rating; challenger tier · 88 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 43 out of every 100 times Brunclik wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
