ALT MARKETS
Handicap A +1.5 games @1.96/1.96 — model cover prob null, no independent margin read → skip.
Total 21.5 O2.00/U1.94 — model 49.4/50.6 vs market ~50/50 → no edge.
VERDICT — BET Waltert ML 1.0u @ 2.16 (Betfair)
ML model (51.3%) disagrees with exchange (46.3%); ELO disagrees the other way, so the
qualitative read is the tiebreaker and it points hard at the dog: textbook title-letdown
on Sherif plus an extreme fatigue differential vs a rested opponent. p(Waltert) ≈ 0.52.
Effective odds 2.10 (5% comm) → edge ~4.4%; min odds 1.05/0.52 = 2.02 ≤ 2.16 → clears.
Edge <5% → 1.0u. Risks: Sherif has won straight through this workload (10-0), yesterday's
final was shortened, ELO 60/40 against, Waltert's last match was a 1-6 4-6 dud.
