STAGE 2 BANKROLL MATRIX · 2-1-2 MANHATTAN · 40U / 3-SHOE
2-1-2 Manhattan Progression — 40-Unit Bankroll & 3-Shoe (216-Hand) Risk-of-Ruin Matrix
For a 40-unit roll spanning 216 hands (3 shoes), 2-1-2 Manhattan Progression (2-1-2-3-4-5) audits a session-bounded cycle-span under matrix M407-0, where the 60-unit table roof and -20u/+10u barriers yield 53.21% ruin versus 31.18% upside completion. 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.
