STAGE 2 STRESS TEST · 2-1-2 MANHATTAN VS FLAT BETTING

2-1-2 Manhattan Progression vs. Flat 1-Unit Baseline — Ping-Pong Chop Shoe under No-Commission Banker 6 Half-Pay (70-Hand Stress Test)

Within table-capped testbed S272-0, a 65-unit bankroll facing 70 coups of No-Comm Chop (chop) and a 50-unit maximum wager tracks 13.66% ruin (1.66u expected loss) on 2-1-2 Manhattan Progression versus 5.93% ruin (1.06u expected loss) on Flat 1-Unit Baseline. 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.
