STAGE 2 STRESS TEST · 2-1-2 MANHATTAN VS FLAT BETTING
2-1-2 Manhattan Progression vs. Flat 1-Unit Baseline — Three-Shoe 15% Tie Density on Even-Money Player Wagers (210-Hand Stress Test)
Combinatorial stress ledger S280-0 charts 2-1-2 Manhattan Progression versus Flat 1-Unit Baseline across 210 coups (130u bankroll, 85u max bet), demonstrating that 1.2351% house edge and 4-hand runs enforce 21.33% vs 8.79% ruin along the multi-coup footprint. 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.
