STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 200U / 5-SHOE

Grand Martingale (2x+1) — 200-Unit Bankroll & 5-Shoe (360-Hand) Risk-of-Ruin Matrix

Under discrete-time boundary rules in M145-0, pairing Grand Martingale (2x+1) with 200 units across 5 shoes (360 hands) and a 80-unit maximum profiles a 46.51% stop-loss absorption rate, surviving at most 7 adverse steps before commission-adjusted progression-curve 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.

Reference 8-deck shoe for Matrix Cell M145 (Grand Martingale (2x+1), 200u bankroll, 360 hands). Big Road and Bead Plate show Banker (red) and Player (blue); derived roads record structural symmetry.

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 M145 · STOP-LOSS & STOP-WIN GEOMETRY

Grand Martingale 200u session-bounded exposure Across 360 Hands (M145)

Audit M145-1 calibrates the commission-adjusted threshold of Grand Martingale when anchored to 200 units and a 360-hand (5-shoe) schedule: the 80-unit maximum wager restricts recovery at step 7, locking in a 46.51% stop-loss frequency and $1961 in mathematical friction.

Under asymmetric boundary rules in M145-2, pairing Grand Martingale (2x+1) with 200 units across 5 shoes (360 hands) and a 80-unit maximum dissects a 46.51% stop-loss absorption rate, surviving at most 7 adverse steps before absorbing-barrier drawdown-slope truncation.

80u Ceiling Collisions & Grand Martingale Turnover (5 Shoes)

Audit M145-3 evaluates the combinatorial footprint of Grand Martingale when anchored to 200 units and a 360-hand (5-shoe) schedule: the 80-unit maximum wager restricts recovery at step 7, locking in a 46.51% stop-loss frequency and $1961 in mathematical friction.

Under non-stationary boundary rules in M145-4, pairing Grand Martingale (2x+1) with 200 units across 5 shoes (360 hands) and a 80-unit maximum audits a 46.51% stop-loss absorption rate, surviving at most 7 adverse steps before session-bounded capital-runway truncation.

  • Cell M145 rule: lock the -100u stop on your 200u Grand Martingale stack across 360 hands.
  • Matrix M145 verifies 39.22u ($1961) in house hold over 2207u of Grand Martingale action.
  • Scoreboard check M145: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (session-bounded exposure) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 200 units to a 5-shoe session lets Grand Martingale (2x+1) overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 360 hands, Grand Martingale generates 2207u in action, 39.22u in expected loss, and a 46.51% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell Grand Martingale bettors whether Banker (red) or Player (blue) is due during a 360-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.
