STAGE 2 STRESS TEST · 2-1-2 MANHATTAN VS FLAT BETTING
2-1-2 Manhattan Progression vs. Flat 1-Unit Baseline — 11-Hand Banker Run under No-Commission Banker 6 Half-Pay (74-Hand Stress Test)
Combinatorial stress ledger S273-0 profiles 2-1-2 Manhattan Progression versus Flat 1-Unit Baseline across 74 coups (90u bankroll, 65u max bet), demonstrating that 1.4579% house edge and 11-hand runs enforce 7.69% vs 4.92% ruin along the sequential excursion. Because every 8-deck coup is statistically independent under No-Commission Banker 6 (0.50:1 on 6) (1.4579% edge), progression rules alter drawdown speed and table-cap collisions without changing per-hand expectation.
