2-1-2 Manhattan Progression vs. Flat 1-Unit Baseline — Two-Shoe Strict Alternation on Even-Money Player Wagers (140-Hand Stress Test)

Across 140 resolved and tied deals under Player 1:1 Chop (1.2351% edge), non-stationary comparison S278-0 benchmarks 2-1-2 Manhattan Progression against Flat 1-Unit Baseline on a 95-unit bankroll, showing that 2-hand clusters and a 70-unit ceiling drive 20.44% vs 7.64% stop-loss breaches along the combinatorial decay-rate. 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.
