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

2-1-2 Manhattan Progression vs. Flat 1-Unit Baseline — Four-Shoe 12-Run Volatility under No-Commission Banker 6 (288-Hand Stress Test)

Under 4-Shoe Streak (1.4579% effective edge), absorbing-barrier stress run S282-0 over 288 hands and a 180-unit treasury measures a -41u drawdown (14.70% ruin) for 2-1-2 Manhattan Progression against -22u (9.17% ruin) for Flat 1-Unit Baseline inside a 100-unit cap. 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.

Column 2 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

  1. Column 3 starts, so use Rule 1: compare Column 2 with Column 1, 1 column further back.
  2. Column 2 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 2, the one that just finished, with Column 1.
