STAGE 2 BANKROLL MATRIX · D'ALEMBERT · 500U / 2-SHOE
D'Alembert Pyramid — 500-Unit Bankroll & 2-Shoe (144-Hand) Risk-of-Ruin Matrix
When a 500-unit stack enters a 2-shoe (144-hand) session using D'Alembert Pyramid, session-bounded model M299-0 measures 315u in cumulative action and a 3.90% barrier-absorption probability before the 50-unit table maximum truncates the multi-coup exposure. 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.
