MODELS vs MARKET
Book: Blockx 2.30 / Darderi 1.62 (implied A 41.3%)
Betfair exchange: Blockx 2.68 / Darderi 1.59 (implied A 37.3%; eff. 2.596 after 5% comm = 38.5%)
ELO prob A: 39.7% | ML prob A: 36.5% | Sim/composite A: 45.2%

an edge vs the executable price: 45.2 - 38.5 = 6.7% - a lone-model signal.
ELO/ranking sanity: Darderi rank 25 vs Blockx 36, consistent with the ~60/40 ELO split. No divergence flag.

Deeper: Madrid SF run in April (beat Ruud 1987, Cerundolo 1914, FAA 1850) - real clay pedigree, but 3 months old.

Live-event read: Darderi is 2-0 at Estoril incl. a 6-0 6-1 demolition; winning form despite the load.
FATIGUE (precomputed)
Blockx: 3 matches/14d, 9 sets, 498 court-min (avg 166/match - his wins are long grinds), played 07-24.
Darderi: 6 matches/14d, 18 sets, 747 court-min, 3 back-to-backs, played 07-24 (Bastad final run + Estoril).
Court-time diff 249 min over the 60-min threshold = Darderi disadvantaged. Age 24 = baseline, no modulation.
But Blockx is not fresh either: two straight 3-set grinds here, and both men played yesterday.

Venue: both 2-0 at Estoril this week. Neutral.

ALT MARKETS
Handicap A +2.5 @1.98 / B -2.5 @1.94 - model handicap probs null, no independent margin read, no play.
Total 22.5: O 2.02 / U 1.91; model U 53.5% vs implied 52.4% = 1.1% edge, far below bar, no play.
GATES
G1 edge-origin: FAIL - stripped of fatigue, the Blockx edge rests on the lone composite sim (45.2% vs 38.5% exec = 6.7%); ELO (39.7%) and ML (36.5%) sit at/below the exchange, so the consensus-of-models edge is ~1-2%, under the 5% bar. The only thing lifting it is Darderi schedule - fatigue cannot create the staked edge.
G2 consensus: FAIL - market AND ML both favor Darderi; no H2H available, and live this-event evidence points the wrong way (Darderi 6-0 6-1 DOM in R16, beat a Strong QF opponent while carrying the load).
G3 fatal-risk: PASS - no self-negating risk identified, but moot given G1/G2.
VERDICT: PASS. Darderi 747 court-minutes and 3 back-to-backs are the whole temptation, and fatigue may only confirm an edge, never create one. The numerical case for Blockx is a single-model signal contradicted by ELO, ML and the exchange, while Darderi live Estoril form is excellent. Thin under-22.5 and unmodeled handicap offer nothing better. Predicted winner: L. Darderi.
