2-Deck Four-Pip Card Depletion at 10% Penetration (5% Audit DEP127)

How Four-Pip Card Depletion at 10% Depth Impacts 2D (5% Vig)

Audit DEP127 evaluates a 2-deck (104-card) shoe at 10% penetration where 1 of 8 Four-Pip Card cards have exited, leaving 7 Rank-4 cards inside the 94-card stub with Banker EV at -0.9618% under 5%.

In six-card resolution tree DEP127 (2D at 10% depth, 94 cards left), removing 4s produces the (dep127-rank-4) single largest per-card shift toward (94c) banker (and away from player) (dep127-rank-4·94c) of any rank in the shoe; removing 1 of 8 Rank-4 cards (+1.19 bps weight) leaves Banker at -0.9618% EV under 5%.

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP127 · 2D)

Cut-card protocol at 10% depth in DEP127 (2D, 94 stub cards containing 7 Rank-4 cards) ensures the shoe reshuffles long before 5% house hold (0.9618% Banker / 1.3332% Player) is overturned.

  • DEP127 (2D 10%): 94/104 cards with 7/8 Rank-4 (3A).
  • DEP127 (Rank-4 split): 45.9003% Banker, 44.5671% Player, 9.5326% Tie in 94 2D cards (3B).
  • DEP127 (5% Vig EV): -0.9618% Banker, -1.3332% Player, -14.2065% Tie, 0.9317 SD at 10% (3C).
  • DEP127 (2D roads): red/blue marks log Big Road columns, never 7 Rank-4 stub count (3D).
Table Reality Check

Myth vs. Truth

MythWhen 1 Four-Pip Card cards leave a 2D shoe by 10% depth (DEP127), 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 (7/8 in 94 cards); Banker carries a -0.9618% expectation under 5%.
