FATIGUE
Valentova: 6 matches/14d, 18 sets, 513 court min, 2 back-to-backs, 3-set TB grind yesterday.
Snigur: 3 matches/14d, 9 sets, 281 court min, no back-to-backs.
Raw gap 232 min -> Valentova disadvantaged; age modulation: Valentova is 19, recovers fast — softened one tier to "slight edge Snigur". Snigur 24, baseline.
NARRATIVE
Let-down: none in window for either (Snigur won a weak-field Eastbourne final 34d ago — outside window). Venue: both 3-0 at this event. Surface transition: none — both on Prague clay all week. TITLE: Snigur — Eastbourne 34d ago (grass, final opponent ELO 1481; farmed field).
ALT MARKETS
Handicap: A -1.5 @1.92 / B +1.5 @1.99. Model margin probs are internally inconsistent (A +0.5 covers 46.5% vs sim match prob 55.7%) — unreliable anchor. Independent margin read: Snigur's recent losses vs quality are blowouts (2-6 3-6 Krueger, 0-6 4-6 Stearns), which negates a B +1.5 cover thesis (G3-type risk); Valentova covering -1.5 is unsupported by her own grind-heavy scorelines. No stake.
Total 21.5: Under edge 0.513 - 0.510 = +0.3% — negligible. No stake.
GATES
G1 edge-origin: FAIL — stripped of fatigue/narrative, blended model prob for A (~0.56-0.61) vs Betfair effective 57.4% gives at most ~3-4%; the sim itself sits below the market. No 5% numeric edge on any side or market.
G2 consensus: FAIL (for any Snigur play) — market, ML and ELO all favour Valentova; Snigur's only support is a weak-field run, not hard independent evidence.
G3 fatal-risk: FAIL (for any cover/dog play) — Snigur's blowout losses to quality opposition directly negate a +1.5/ML dog thesis; Valentova's 513-min load caps any lay of the -1.5.
VERDICT: PASS. The exchange has this priced right: Valentova's superior opponent quality this week is offset by her heavy court time (softened by age 19), and the simulation agrees with the market within noise. No market on this match clears the bar.
