value_pick A · edge +22.2% · bot_suggestion: BET 2.5u on Liu
→ BOTH models sit far above market on Liu; alignment BROKEN in Liu's favor.
FORM
C. Liu (A): riding a huge win streak but entirely vs ITF/low fields —
W75 Trnava, W35 Boca Raton, plus "Finals" over 1400-1700 ELO opp.
Wimbledon MD: d Sonmez (1744) 7-5 6-3, d Vandewinkel (1514) in 3.
Opponent ceiling ~1780. No elite scalps anywhere.
C. Gauff (B): genuine elite. Rome QF/SF run beating M. Andreeva (1995),
Cirstea (1908), reached Rome Final (l. Svitolina 1989). Wimbledon MD:
d Korpatsch 6-2 6-1 (DOM), d Sierra in 3. Operates 300-500 ELO above
anyone Liu has faced.
FATIGUE
A: 5 matches/14d, ~352 court-min, back-to-back 2 → heavily loaded.
B: 3 matches/14d, ~225 court-min, fresh by comparison.
|court diff| 127min > 60 → fatigue edge AGAINST Liu.
NARRATIVE
Let-down: none live for Gauff (last Final Rome 05-16, l.).
Liu won a Wimbledon-labelled "Final" 06-25 (8d, WEAK window) — not material.
Venue/title: no signal that helps the underdog.
VERDICT — PASS
The +22% "edge" is a pure ELO/ML inflation artifact: Liu's rating was
padded by stacking wins over sub-1800 ITF fields, so the models
hallucinate her at 28-45% vs a top-tier Gauff who beats 1900-2000 ELO
players. Class gap is enormous, fatigue also favors Gauff, and there is
no qualitative signal validating the model. Market at 1.04 is efficient.
Backing Liu at 17.0 is a trap. No bet.
