Consistent bounce, medium-fast: neutral conditions, no style favored.

WHAT THE ESTIMATE IS BASED ON

›Tour Elo: 1877 vs 1841 — favorite by rating

›Challenger tier · 360 matches in the favorite's track record

›Elo estimate (not the ATP factor model): these are softer, less-analyzed markets

BREAKDOWN · ELO ESTIMATE

The model makes J. De Jong the favorite with a 55% win probability, against H. Mayot's 45% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.81; the offered odds are around @1.75 (a 57% implied), virtually the same as what the market prices in.

Several factors explain the number: 1877 vs 1841 — favorite by rating; challenger tier · 360 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 45 out of every 100 times Mayot wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
