›Tour Elo: 1884 vs 1668 — favorite by rating
›ATP qualifying / early round · 347 matches in the favorite's track record
›Elo estimate (not the ATP factor model): qualifying draws have no clean main-tour history
!Qualifying/soft context: Elo estimate only — read the round context (already-through, lucky loser, dead rubber) from the dossier; it is not a proven edge.
The model makes A. Walton the favorite with a 78% win probability, against J. Boulais's 22% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.29; the offered odds are around @1.11 (a 90% implied), slightly below the market, so the model is a touch more cautious.
Several factors explain the number: 1884 vs 1668 — favorite by rating; atp qualifying / early round · 347 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 22 out of every 100 times Boulais wins. And above all, in Challenger/ITF the value edge is not proven live, so treat it as a reference, not an opportunity. Watch out for: Qualifying/soft context: Elo estimate only — read the round context (already-through, lucky loser, dead rubber) from the dossier; it is not a proven edge..
