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

2-1-2 Manhattan Progression vs. Flat 1-Unit Baseline — Three-Shoe Adverse 8-Run on Even-Money Player Wagers (216-Hand Stress Test)

Within stochastic testbed S279-0, a 140-unit bankroll facing 216 coups of Player 1:1 Streak (streak) and a 90-unit maximum wager audits 15.92% ruin (4.34u expected loss) on 2-1-2 Manhattan Progression versus 8.20% ruin (2.77u expected loss) on Flat 1-Unit Baseline. 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.
