STAGE 2 BANKROLL MATRIX · CONTRA D'ALEMBERT · 300U / 1-SHOE
Contra D'Alembert Press — 300-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix
For a 300-unit roll spanning 72 hands (1 shoes), Contra D'Alembert Press (+1 on win / -1 on loss) calibrates a eight-deck exposure under matrix M321-0, where the 40-unit table roof and -150u/+75u barriers yield 3.54% ruin versus 44.68% 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.
