NARRATIVE
Let-down: none (B lost SF, not a title; NOTE-level at most). No Finals in either window.
Venue: no Estoril history in window for either. Title recency: none.
VERDICT — PASS
Direction of any edge is toward Wawrinka (fatigue + fresh), but the executable price
kills it: Betfair A 3.00 → eff 2.90 → needs 34.5%; model has A at 25.8% and even a
generous fatigue bump (~30%) falls short (min odds at p=0.30 would be 3.50).
B side is worse: model 74.2% vs exchange-implied 90.5% eff → −16pt edge. The "soft"
book 1.41 on B is a stale quote the exchange contradicts, not value. No handicap or
totals priced. No bettable market → PASS.
