2-Deck Eight-Pip Card Depletion at 75% Penetration (4% Audit DEP169)

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.

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

Audit DEP169 evaluates a 2-deck (104-card) shoe at 75% penetration where 7 of 8 Eight-Pip Card cards have exited, leaving 1 Rank-8 cards inside the 26-card stub with Banker EV at -0.5083% under 4%.

Combinatorial weighting in DEP169 (26 cards left from 104 at 75% depth) is governed by two rules: on banker total 3, (dep169) banker draws against every player (2d-75%) third card except 8; removing (dep169·2d-75%) 8s eliminates banker 3's sole standing exception, and three-quarters of the shoe (dep169-2d) has been dealt and winning (1/8) banker wagers return 0.96 units (dep169-2d·1/8) net per unit risked (-0.50 bps per Rank-8 removed).

  • DEP169 (4% Vig EV): -0.5083% Banker, -1.3276% Player, -14.2074% Tie, 0.9394 SD at 75% (3C).
  • DEP169 (2D roads): red/blue marks log Big Road columns, never 1 Rank-8 stub count (3D).
Table Reality Check

Myth vs. Truth

MythWhen 7 Eight-Pip Card cards leave a 2D shoe by 75% depth (DEP169), 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-8 stub counts (1/8 in 26 cards); Banker carries a -0.5083% expectation under 4%.
