2-Deck Four-Pip Card Depletion at 40% Penetration (4% Audit DEP129)

Removing 4 of 8 Four-Pip Card (Rank-4) cards at 40% penetration of a 2-deck (104-card) shoe leaves 4 Rank-4 cards inside a 62-card stub (DEP129), producing 45.9023% Banker wins, 44.5650% Player wins, 9.5326% Ties, and a 0.4988% Banker house edge under 4%.

FINITE-SHOE ENUMERATION · DEP129

How Four-Pip Card Depletion at 40% Depth Impacts 2D (4% Vig)

When a 2D shoe reaches 40% cut-card depth (62 of 104 cards undealt, state DEP129) with 4 Four-Pip Card cards removed and 4 remaining, Player wins 44.5650% (1.3373% edge) while Banker wins 45.9023% (0.4988% edge under 4%).

Removing 4s produces the (DEP129-Rank-4) single largest per-card shift toward (62c) Banker (and away from Player) (DEP129-Rank-4·62c) of any rank in the shoe. Because 4 of 8 Four-Pip Card cards are absent in DEP129 at 40% 2D penetration (62 cards left), per-card sensitivity (+1.19 bps) interacts directly with mid-early 40% penetration depth (DEP129) under reduced 4% Banker commission (Rank-4) (0.96:1 payout).

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP129 · 2D)

Whether DEP129 is observed in double-deck European salon privé carriers and two-deck shoe pits at 40% depth (62/104 cards left, 4 Rank-4 remaining), 4% Vig settlement locks Banker EV at -0.4988% and Player EV at -1.3373% with 9.5326% Ties.

  • DEP129 (2D 40%): 62/104 cards with 4/8 Rank-4 (6A).
  • DEP129 (Rank-4 split): 45.9023% Banker, 44.5650% Player, 9.5326% Tie in 62 2D cards (6B).
  • DEP129 (4% Vig EV): -0.4988% Banker, -1.3373% Player, -14.2062% Tie, 0.9347 SD at 40% (6C).
  • DEP129 (2D roads): red/blue marks log Big Road columns, never 4 Rank-4 stub count (6D).
Table Reality Check

Myth vs. Truth

MythWhen 4 Four-Pip Card cards leave a 2D shoe by 40% depth (DEP129), 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 (4/8 in 62 cards); Banker carries a -0.4988% expectation under 4%.
