2-Deck Four-Pip Card Depletion at 75% Penetration (4% Audit DEP133)

Removing 7 of 8 Four-Pip Card (Rank-4) cards at 75% penetration of a 2-deck (104-card) shoe leaves 1 Rank-4 cards inside a 26-card stub (DEP133), producing 45.9052% Banker wins, 44.5621% Player wins, 9.5327% Ties, and a 0.4931% Banker house edge under 4%.

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.

How Four-Pip Card Depletion at 75% Depth Impacts 2D (4% Vig)

Card-removal benchmark DEP133 measures Four-Pip Card (Rank-4) scarcity at 75% depth in a 2-deck shoe: 7 removed ranks leave 1 in the 26-card remainder, shifting Banker win share to 45.9052% (0.4931% edge, 4% Vig).

Tracking DEP133 across 26 remaining 2D cards (75% depth) shows that removing 4s produces the (dep133-rank-4) single largest per-card shift toward (26c) banker (and away from player) (dep133-rank-4·26c) of any rank in the shoe. With 7 Rank-4 cards gone (+1.19 bps unit sensitivity), Banker expectation is -0.4931% (4% Vig) vs -1.3431% on Player.

  • DEP133 (4% Vig EV): -0.4931% Banker, -1.3431% Player, -14.2058% Tie, 0.9382 SD at 75% (5C).
  • DEP133 (2D roads): red/blue marks log Big Road columns, never 1 Rank-4 stub count (5D).
Table Reality Check

Myth vs. Truth

MythWhen 7 Four-Pip Card cards leave a 2D shoe by 75% depth (DEP133), Big Eye Boy red or blue marks show whether Banker or Player will win next.
TruthDerived-road red and blue marks only compare Big Road column lengths and never track Rank-4 stub counts (1/8 in 26 cards); Banker carries a -0.4931% expectation under 4%.
