STAGE 2 BANKROLL MATRIX · CONTRA D'ALEMBERT · 20U / 10-SHOE

Contra D'Alembert Press — 20-Unit Bankroll & 10-Shoe (720-Hand) Risk-of-Ruin Matrix

When a 20-unit stack enters a 10-shoe (720-hand) session using Contra D'Alembert Press, variance-scaled model M303-0 audits 806u in cumulative action and a 94.80% barrier-absorption probability before the 100-unit table maximum truncates the house-edge-anchored escalation. 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 M303 (Contra D'Alembert Press, 20u bankroll, 720 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

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

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

  1. Column 4 goes down to Row 3, so use Rule 2: look 3 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.

Testing Contra D'Alembert (+1 on win / -1 on loss) at 20 units across 720 coups in cell M303-1 tracks a 94.80% chance of striking the -10-unit stop-loss, while the 100-unit pit ceiling and 1.058% Banker edge impose 9.72u ($972) in expected erosion.

When a 20-unit stack enters a 10-shoe (720-hand) session using Contra D'Alembert Press, eight-deck model M303-2 measures 806u in cumulative action and a 94.80% barrier-absorption probability before the 100-unit table maximum truncates the asymmetric threshold.

100u Ceiling Collisions & Contra D'Alembert Turnover (10 Shoes)

Testing Contra D'Alembert (+1 on win / -1 on loss) at 20 units across 720 coups in cell M303-3 maps a 94.80% chance of striking the -10-unit stop-loss, while the 100-unit pit ceiling and 1.058% Banker edge impose 9.72u ($972) in expected erosion.

When a 20-unit stack enters a 10-shoe (720-hand) session using Contra D'Alembert Press, bankroll-constrained model M303-4 documents 806u in cumulative action and a 94.80% barrier-absorption probability before the 100-unit table maximum truncates the bankroll-constrained excursion.

  • Cell M303 rule: lock the -10u stop on your 20u Contra D'Alembert stack across 720 hands.
  • Matrix M303 inspects 9.72u ($972) in house hold over 806u of Contra D'Alembert action.
  • Scoreboard check M303: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (drawdown-weighted stake-velocity) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 20 units to a 10-shoe session lets Contra D'Alembert Press overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 720 hands, Contra D'Alembert generates 806u in action, 9.72u in expected loss, and a 94.80% 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 720-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.
