STAGE 2 STRESS TEST · GRAND MARTINGALE VS FLAT BETTING
Grand Martingale (2x+1) vs. Flat 1-Unit Baseline — Three-Shoe 15% Tie Density on Even-Money Player Wagers (210-Hand Stress Test)
Pairing a 130-unit bankroll against 210 hands of Player High-Tie (1.2351% edge) in cell S126-0 models Grand Martingale at 52.85% ruin and -37u peak volatility-band, whereas Flat Betting records 8.79% ruin and -12u below the 85-unit ceiling. Because every 8-deck coup is statistically independent under Even-Money Player Side (1.235% edge) (1.2351% edge), progression rules alter drawdown speed and table-cap collisions without changing per-hand expectation.
