How Nine-Pip Card Depletion at 75% Depth Impacts 8D (4% Vig)

Quantitative proof DEP448 documents 8D rank depletion at 75% depth: 28 exited Rank-9 cards leave 4 of 32 in the 104-card stub, generating 45.8587% Banker wins (-0.6015% EV under 4% Vig) and 44.6258% Player wins.

Why does Rank-9 carry a -0.23 bps per-card effect in DEP448? Rank 9 paired with (DEP448) any ten or face card (8D-75%) creates an unbeatable two-card Natural (DEP448·8D-75%) 9 that halts all third-card drawing on both sides, and at 75% penetration (4 Nine-Pip Card cards left in 104 8D cards), three-quarters of the shoe (dep448-8d) has been dealt and winning (4/32) banker wagers return 0.96 units (dep448-8d·4/32) net per unit risked.

Table Reality Check

Myth vs. Truth

MythWhen 28 Nine-Pip Card cards leave a 8D shoe by 75% depth (DEP448), 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 (4/32 in 104 cards); Banker carries a -0.6015% expectation under 4%.
