BREAKDOWN · ELO ESTIMATE

The model makes P. Bar Biryukov the favorite with a 60% win probability, against J. Cui's 40% — a solid favorite, though Cui keeps real chances. Converted to odds, that probability is worth about @1.66; the offered odds are around @1.70 (a 59% implied), virtually the same as what the market prices in.

Several factors explain the number: 1736 vs 1664 — favorite by rating; challenger tier · 221 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 40 out of every 100 times Cui wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
