STAGE 2 BANKROLL MATRIX · 2-1-2 MANHATTAN · 20U / 1-SHOE
2-1-2 Manhattan Progression — 20-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix
Case M401-0 tracks the table-capped 2-1-2 Manhattan Progression (2-1-2-3-4-5) across a 20-unit bankroll and a 72-hand (1-shoe) window, where a 40-unit table ceiling and 10-unit stop-loss produce a 36.46% ruin rate while calibrates an average stake cadence of 1.10x and 0.94u ($24) in theoretical house-edge toll. Every 8-deck hand remains statistically independent (45.86% Banker, 44.62% Player, 9.52% Tie), meaning progression sizing reshapes session variance without altering the house edge.
