RECENT FORM (last 5)

W vs Minnen 1684-str 6-1 6-3 DOM; L vs Bronzetti (Wimb QF, grass); L vs Cirstea (grass).

Hontama (B): W vs Sakatsume 1683-str 6-2 6-2 DOM (QF, 2 sets); W vs Lu 1468 6-3 6-3 DOM;
W vs Day 1692-str 7-6 6-3 6-4 GRIND; L vs Tagger (Prague, clay); W vs Parry (Prague, clay).
Path: 3 wins deep at Vancouver, match-sharp. Shape SHARPENING (DOM 6-2 6-2 over Strong Sakatsume).
Transitioned clay->hard before Vancouver but now 3 hard wins in = acclimated.
FATIGUE
Both played QF yesterday (07-30). Inglis WON A 3-SET match yesterday -> calibrated 3-set-hangover
haircut -4.5pp on Inglis (age 28 baseline, no age modulation). True A ~0.474 after haircut.
Hontama won a 2-SET match yesterday (6-2 6-2) -> no extra-set toll; fresher and more dominant in
the most recent match despite heavier cumulative load (566min/14d = context, not an edge).
Net: fatigue KILLS the thin A edge rather than confirming it — the tired-side toll is on Inglis.
NARRATIVE
No first-Final let-down spot active this week for either. Both sharp, both deep runs. No transition
risk on Inglis (hard->hard). Hontama clay->hard already absorbed over 3 wins.
GATES
G1 edge-origin: FAIL — A ML edge vs commission-adj Betfair (eff 2.026, 1/2.026=0.494) = 0.519-0.494
= 2.5%, below the 5% bar BEFORE any fatigue adj. 3-set hangover then pushes A to ~0.47 (negative).
G2 consensus: stake-tier only (never blocks) — n/a, no qualifying edge.
G3 fatal-risk: n/a (no margin bet staked).
MARKET CHOICE
ML: A edge 2.5% (<5%) -> PASS. B has no model support (models lean A pre-fatigue).
Handicap: model A covers -0.5 only 52.5%; line quoted A -1.5 @1.92 => cover < 50%, no edge. Cover
thesis also can't lean on fatigue. PASS. AH: A -1.5 @ 1.92 / B +1.5 @ 1.98 (both ~coin-flip).
Total: model over 20.5 = 53.7% -> ~51% at the 21.0 line vs over @2.0 (impl 0.50) = ~1% edge. PASS.
VERDICT: PASS. Best model edge (A ML) is only ~2.5% at the executable Betfair price — below the 5%
bar — and the 3-set-hangover haircut lands on that same A side, erasing it. Hontama is equally
match-sharp and objectively fresher (2-set win vs Inglis's 3-setter). No market clears its bar.
