STAGE 2 BANKROLL MATRIX · 2-1-2 MANHATTAN · 40U / 1-SHOE

2-1-2 Manhattan Progression — 40-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix

Under step-indexed boundary rules in M406-0, pairing 2-1-2 Manhattan Progression with 40 units across 1 shoes (72 hands) and a 40-unit maximum maps a 18.60% stop-loss absorption rate, surviving at most 6 adverse steps before asymmetric survival-window 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 M406 (2-1-2 Manhattan Progression, 40u bankroll, 72 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

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.

MATRIX CELL M406 · STOP-LOSS & STOP-WIN GEOMETRY

2-1-2 Manhattan 40u table-capped distribution Across 72 Hands (M406)

Audit M406-1 documents the eight-deck trajectory of 2-1-2 Manhattan 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 18.60% stop-loss frequency and $26 in mathematical friction.

Under absorbing-barrier boundary rules in M406-2, pairing 2-1-2 Manhattan Progression with 40 units across 1 shoes (72 hands) and a 40-unit maximum benchmarks a 18.60% stop-loss absorption rate, surviving at most 6 adverse steps before bankroll-constrained stake-velocity truncation.

40u Ceiling Collisions & 2-1-2 Manhattan Turnover (1 Shoes)

Audit M406-3 models the bankroll-constrained cycle-span of 2-1-2 Manhattan 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 18.60% stop-loss frequency and $26 in mathematical friction.

Under capital-bounded boundary rules in M406-4, pairing 2-1-2 Manhattan Progression with 40 units across 1 shoes (72 hands) and a 40-unit maximum computes a 18.60% stop-loss absorption rate, surviving at most 6 adverse steps before variance-scaled cycle-span truncation.

  • Cell M406 rule: lock the -20u stop on your 40u 2-1-2 Manhattan stack across 72 hands.
  • Matrix M406 tracks 1.04u ($26) in house hold over 87u of 2-1-2 Manhattan action.
  • Scoreboard check M406: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (table-capped distribution) 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 2-1-2 Manhattan Progression overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 72 hands, 2-1-2 Manhattan generates 87u in action, 1.04u in expected loss, and a 18.60% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell 2-1-2 Manhattan 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.
