STAGE 2 STRESS TEST · 2-1-2 MANHATTAN VS FLAT BETTING
2-1-2 Manhattan Progression vs. Flat 1-Unit Baseline — 18% Tie-Heavy Shoe under No-Commission Banker 6 Half-Pay (80-Hand Stress Test)
When No-Comm High-Tie (high-tie) injects a 5-hand extreme run and 15 tie pushes (18.75% Tie density) over 80 coups, finite-shoe audit S274-0 inspects 2-1-2 Manhattan Progression at 1.90u expected erosion (11.65% ruin) compared with 1.21u (5.73% ruin) for Flat 1-Unit Baseline on 85 units. 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.
