STAGE 2 BANKROLL MATRIX · D'ALEMBERT · 40U / 1-SHOE

D'Alembert Pyramid — 40-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix

Under multi-coup boundary rules in M281-0, pairing D'Alembert Pyramid with 40 units across 1 shoes (72 hands) and a 40-unit maximum benchmarks a 21.58% stop-loss absorption rate, surviving at most 6 adverse steps before capital-bounded envelope truncation. 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.

MATRIX CELL M281 · STOP-LOSS & STOP-WIN GEOMETRY

D'Alembert 40u commission-adjusted escalation Across 72 Hands (M281)

Audit M281-1 models the finite-shoe turnover of D'Alembert when anchored to 40 units and a 72-hand (1-shoe) schedule: the 40-unit maximum wager restricts recovery at step 6, locking in a 21.58% stop-loss frequency and $30 in mathematical friction.

Under session-bounded boundary rules in M281-2, pairing D'Alembert Pyramid with 40 units across 1 shoes (72 hands) and a 40-unit maximum computes a 21.58% stop-loss absorption rate, surviving at most 6 adverse steps before step-indexed boundary truncation.

STEP ESCALATION & TURNOVER AUDIT

40u Ceiling Collisions & D'Alembert Turnover (1 Shoes)

Audit M281-3 inspects the variance-scaled decay-rate of D'Alembert when anchored to 40 units and a 72-hand (1-shoe) schedule: the 40-unit maximum wager restricts recovery at step 6, locking in a 21.58% stop-loss frequency and $30 in mathematical friction.

Under step-indexed boundary rules in M281-4, pairing D'Alembert Pyramid with 40 units across 1 shoes (72 hands) and a 40-unit maximum verifies a 21.58% stop-loss absorption rate, surviving at most 6 adverse steps before multi-coup escalation truncation.

  • Cell M281 rule: lock the -20u stop on your 40u D'Alembert stack across 72 hands.
  • Matrix M281 verifies 1.20u ($30) in house hold over 94u of D'Alembert action.
  • Scoreboard check M281: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (commission-adjusted escalation) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 40 units to a 1-shoe session lets D'Alembert Pyramid overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 72 hands, D'Alembert generates 94u in action, 1.20u in expected loss, and a 21.58% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell D'Alembert bettors whether Banker (red) or Player (blue) is due during a 72-hand run.
TruthOn Big Eye Boy, Small Road, and Cockroach Pig, red indicates repeating column structure and blue indicates breaking structure; neither color represents Banker or Player.
