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

Depletion matrix entry DEP178 pairs 2D (104 cards) at 75% penetration with 7 removed Nine-Pip Card cards (1 left in 26 cards), fixing per-hand volatility at 0.9397 and Banker house hold at 0.5059% (4% Vig).

In 2D audit DEP178 (26/104 stub at 75% depth), when 9s are depleted (dep178-rank-9) late in the shoe, more (26c) hands bypass four-card natural resolution (dep178-rank-9·26c) and enter the five- and six-card tableau. Removing 7 Rank-9 cards (-0.23 bps per card) alongside 4% Vig rules sets Tie hold to 14.2070% (9.5326% frequency).

Table Reality Check

Myth vs. Truth

MythWhen 7 Nine-Pip Card cards leave a 2D shoe by 75% depth (DEP178), 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-9 stub counts (1/8 in 26 cards); Banker carries a -0.5059% expectation under 4%.
