STAGE 2 BANKROLL MATRIX · CONTRA D'ALEMBERT · 40U / 3-SHOE

Contra D'Alembert Press — 40-Unit Bankroll & 3-Shoe (216-Hand) Risk-of-Ruin Matrix

For a 40-unit roll spanning 216 hands (3 shoes), Contra D'Alembert Press (+1 on win / -1 on loss) benchmarks a table-capped boundary under matrix M307-0, where the 60-unit table roof and -20u/+10u barriers yield 55.68% ruin versus 30.49% 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.

Reference 8-deck shoe for Matrix Cell M307 (Contra D'Alembert Press, 40u bankroll, 216 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

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

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

Common table reading watchout: Comparing the wrong columns. Compare Column 2, the one that just finished, with Column 1.

Small Road Mark #2

Column 4 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).

  1. Column 5 starts, so use Rule 1: compare Column 4 with Column 2, 2 columns further back.
  2. Column 4 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).

Common table reading watchout: Comparing the wrong columns. Compare Column 4, the one that just finished, with Column 2.

Cockroach Pig Mark #2

This bead is at Row 2. Column 2 has a bead at Row 2 too → red (=).

  1. Column 5 goes down to Row 2, so use Rule 2: look 3 columns back, at Column 2.
  2. Column 2 has a bead at Row 2 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 2 stopped exactly one row above this bead.

Combinatorial ledger M307-3 inspects Contra D'Alembert (+1 on win / -1 on loss) at 40 units and 216 hands (3 shoes), proving that a 60-unit table ceiling and 1.25x average bet multiplier yield 55.68% ruin probability and 3.26u in theoretical house hold.

For a 40-unit roll spanning 216 hands (3 shoes), Contra D'Alembert Press (+1 on win / -1 on loss) verifies a drawdown-weighted distribution under matrix M307-4, where the 60-unit table roof and -20u/+10u barriers yield 55.68% ruin versus 30.49% upside completion.

  • Cell M307 rule: lock the -20u stop on your 40u Contra D'Alembert stack across 216 hands.
  • Matrix M307 calibrates 3.26u ($163) in house hold over 270u of Contra D'Alembert action.
  • Scoreboard check M307: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (stochastic volatility-band) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 40 units to a 3-shoe session lets Contra D'Alembert Press overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 216 hands, Contra D'Alembert generates 270u in action, 3.26u in expected loss, and a 55.68% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell Contra D'Alembert bettors whether Banker (red) or Player (blue) is due during a 216-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.
