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.

Reference 8-deck shoe for Matrix Cell M299 (D'Alembert Pyramid, 500u bankroll, 144 hands). Big Road and Bead Plate show Banker (red) and Player (blue); derived roads record structural symmetry.

Big Road B is Banker, P is Player Roads under it Red (=): repeating Blue (≠): breaking
Step-by-Step Mark Proofs (Rule 1 & Rule 2)
Big Eye Boy Mark #2

This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).

  1. Column 2 goes down to Row 3, so use Rule 2: look 1 column back, at Column 1.
  2. Column 1 stopped at Row 2, one row above → blue (≠).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.

Small Road Mark #2

This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).

  1. Column 3 goes down to Row 3, so use Rule 2: look 2 columns back, at Column 1.
  2. Column 1 stopped at Row 2, one row above → blue (≠).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.

Cockroach Pig Mark #2

Column 4 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

  1. Column 5 starts, so use Rule 1: compare Column 4 with Column 1, 3 columns further back.
  2. Column 4 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 4, the one that just finished, with Column 1.

MATRIX CELL M299 · STOP-LOSS & STOP-WIN GEOMETRY

D'Alembert 500u finite-shoe capital-runway Across 144 Hands (M299)

Testing D'Alembert (+1 on loss / -1 on win) at 500 units across 144 coups in cell M299-1 maps a 3.90% chance of striking the -250-unit stop-loss, while the 50-unit pit ceiling and 1.058% Banker edge impose 4.03u ($101) in expected erosion.

When a 500-unit stack enters a 2-shoe (144-hand) session using D'Alembert Pyramid, step-indexed model M299-2 documents 315u in cumulative action and a 3.90% barrier-absorption probability before the 50-unit table maximum truncates the house-edge-anchored footprint.

50u Ceiling Collisions & D'Alembert Turnover (2 Shoes)

Testing D'Alembert (+1 on loss / -1 on win) at 500 units across 144 coups in cell M299-3 benchmarks a 3.90% chance of striking the -250-unit stop-loss, while the 50-unit pit ceiling and 1.058% Banker edge impose 4.03u ($101) in expected erosion.

When a 500-unit stack enters a 2-shoe (144-hand) session using D'Alembert Pyramid, absorbing-barrier model M299-4 models 315u in cumulative action and a 3.90% barrier-absorption probability before the 50-unit table maximum truncates the asymmetric turnover.

  • Cell M299 rule: lock the -250u stop on your 500u D'Alembert stack across 144 hands.
  • Matrix M299 measures 4.03u ($101) in house hold over 315u of D'Alembert action.
  • Scoreboard check M299: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (finite-shoe capital-runway) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 500 units to a 2-shoe session lets D'Alembert Pyramid overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 144 hands, D'Alembert generates 315u in action, 4.03u in expected loss, and a 3.90% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell D'Alembert bettors whether Banker (red) or Player (blue) is due during a 144-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.
