BREAKDOWN · ELO ESTIMATE

The model makes A. Shelbayh the favorite with a 56% win probability, against R. Seggerman's 44% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.78; the offered odds are around @1.35 (a 74% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: 1712 vs 1670 — favorite by rating; atp qualifying / early round · 273 matches in the favorite's track record; qualifying draws have no clean main-tour history.

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 44 out of every 100 times Seggerman wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity.
