How Four-Pip Card Depletion at 85% Depth Impacts 2D (EZ Bar-7)

Across 112,869,612,134,400 initial 2D permutations, depletion node DEP135 narrows to a 16-card stub (85% depth) holding 1 of 8 Rank-4 cards, where Banker resolves at 45.9055% (-0.9097% EV) and Player at 44.5618% (-1.3437% EV).

Mechanical draw trees in DEP135 reflect how removing 4s produces the (dep135-rank-4) single largest per-card shift toward (16c) banker (and away from player) (dep135-rank-4·16c) of any rank in the shoe. At 85% 2D depth (1 Rank-4 left of 8 in 16 cards, +1.19 bps slope), at 85% cut-card penetration, (dep135-2d) only 15% of the pack (1/8) remains and winning 3-card banker (dep135-2d·1/8) 7 hands push.
