STAGE 2 STRESS TEST · GRAND MARTINGALE VS FLAT BETTING
Grand Martingale (2x+1) vs. Flat 1-Unit Baseline — Four-Shoe 12-Run Volatility under No-Commission Banker 6 (288-Hand Stress Test)
Head-to-head matrix S128-0 subjects Grand Martingale (1-3-7-15-31-63-127) and Flat Betting (1-1-1-1 constant unit) to 288 hands of 4-Shoe Streak (streak) with 180 units and a 100-unit roof, profiles 27.16u versus 4.37u in mathematical house hold and 64.78% versus 9.17% ruin. 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.
