RECENT FORM (last 5 each)
Brooksby (all GRASS/CLAY — no hard-court in window):
07-03 L Sinner (2020) 6-4 6-3 6-4 — competitive loss to #1-class (neutral+)
07-01 W Buse (1585) 6-2 6-2 6-3 — DOM/Avg
06-29 W Vukic (1641) 7-6 6-1 6-1 (orient.) — GRIND->DOM, made Wimb R16
06-24 L Humbert (1730) 6-3 6-2 — straight loss/Strong
06-23 W Vukic (1667) 7-5 6-1 — DOM/Avg
Solid Wimbledon run (R16). Shape STABLE. But LAST MATCH 07-03 = 24 DAYS AGO -> RUST RISK,
plus grass->hard TRANSITION (depressed level + wider margins in match one).
Moutet (ATP form 1-7 in window; only UTS exhibitions since Wimbledon):
07-16..18 3x UTS exhibition losses (Griekspoor/Norrie/Fonseca) — non-tour format, uninformative
06-30 L Giron (1622) 6-4 4-6 5-7 4-6 — Wimb 1st-rd exit, 4 sets
06-22 L Shelbayh (1411) 5-7 4-6 — LOSS to WEAK opp, UNDER-performing
06-18 L ADF (1671) 4-6 3-6
06-16 W Mpetshi Perricard (1731) 7-6 4-6 7-6 — lone quality win, GRIND
Shape FADING hard (1-7 ATP incl. a sub-1450 loss). Hard court not his best surface.
FATIGUE (Step 2 calibration)
Both effectively rested. Brooksby: 0 matches 14d (24d off). Moutet: fatigue flag counts 3 UTS
matches 07-16..18 but last was 9 days ago -> stale label, NOT an extreme spot. Non-factor both sides.
NARRATIVE
No Final in either window -> no let-down. Surface TRANSITION on Brooksby (grass->hard) = rust risk.
ELO/rank check: Moutet ELO-fav AND ranked #35 (agree) BUT 1-7 live form contradicts -> the ELO
is STALE (rates the name, not the collapse). Live form > historical ELO. This is why the market
has moved off ELO onto Brooksby. The 6.8% ELO edge on Moutet is a stale-model artifact.
ALT MARKETS
Handicap line is -0.5 (= moneyline restated; sim A covers 52.3%) — no independent margin edge.
Totals 22.5: under edge -4.0%, over edge -4.2% — both negative. No resimulate warranted.
GATES (evaluated for the only nominally-edged side, Moutet B)
G1 edge-origin: FAIL — the 6.8% edge exists ONLY in ELO; sim is 51% and market 49%. Stripped of
the stale-rating artifact there is no numerical edge; the "edge" is the model failure mode itself.
G2 consensus: FAIL — hard independent evidence runs AGAINST backing Moutet (1-7 ATP, loss to a
1411, Wimbledon 1st-rd exit). No on-surface H2H or live-event support for B.
G3 fatal-risk: FAIL — Moutet's form collapse is real and directly negates a B thesis; units cannot
buy that back.
(Brooksby side: exchange already agrees; edge vs eff price only ~1%, and capped by 24d rust +
grass->hard transition. Below the 5% bar.)
VERDICT: PASS. Genuine coin-flip that the exchange has priced efficiently — Brooksby's rust/transition
roughly offsets Moutet's form collapse, which is exactly why sim and market both sit near 50/50. The
lone ELO split favouring Moutet is a stale-rating artifact contradicted by 1-7 form; no side clears a
5% edge at the executable price with qualitative confirmation. No alt-market edge. No bet.
