2-1-2 Manhattan Progression — 75-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix

Within non-stationary horizon M411-0, a 75-unit treasury backing 2-1-2 Manhattan Progression for 72 hands (1 shoes) faces a 40-unit bet cap that benchmarks 9.87% ruin exposure, 42.90% target attainment at +19u, and 47.23% time-limit expiration. 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 M411 (2-1-2 Manhattan Progression, 75u bankroll, 72 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.

Horizon matrix M411-3 inspects how 2-1-2 Manhattan (2-1-2-3-4-5) behaves inside a 75-unit session budget across 72 coups, showing that a 40-unit pit limit and 38-unit floor generate a 9.87% drawdown-trigger rate alongside 1.20u in expected 8-deck vigorish.

Within sequential horizon M411-4, a 75-unit treasury backing 2-1-2 Manhattan Progression for 72 hands (1 shoes) faces a 40-unit bet cap that verifies 9.87% ruin exposure, 42.90% target attainment at +19u, and 47.23% time-limit expiration.

  • Cell M411 rule: lock the -38u stop on your 75u 2-1-2 Manhattan stack across 72 hands.
  • Matrix M411 audits 1.20u ($30) in house hold over 100u of 2-1-2 Manhattan action.
  • Scoreboard check M411: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (session-bounded decay-rate) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 75 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 100u in action, 1.20u in expected loss, and a 9.87% 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.
