Double-Double Twin Shoe DDT05: 70-Hand 8-Deck Scoreboard & Derived-Road Audit

Catalog shoe DDT05 (seed 204305) captures a repeating 2-bead BB-PP-BB-PP twin columns testing Rule 1 and Rule 2 Case 1 in tandem across 70 dealt 8-deck hands (34 Banker, 29 Player, 7 Tie). Its 30 logical Big Road columns occupy 30 display columns (C1:2B · C2:2P · C3:2B · C4:2P · C5:2B · C6:2P · C7:2B · C8:2P) and generate 60 Big Eye Boy marks (30R/30B), 58 Small Road marks (31R/27B), and 56 Cockroach Pig marks (44R/12B).

Step-by-Step Mark Proofs (Rule 1 & Rule 2)
DDT05 Big Eye Boy Entry #7

This bead is at Row 2. Column 4 has a bead at Row 2 too → red (=).

  1. Column 5 goes down to Row 2, so use Rule 2: look 1 column back, at Column 4.
  2. Column 4 has a bead at Row 2 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 4 stopped exactly one row above this bead.

DDT05 Small Road Entry #6

Column 5 has 2 beads. Column 3 has 2 beads. Same depth → red (=).

  1. Column 6 starts, so use Rule 1: compare Column 5 with Column 3, 2 columns further back.
  2. Column 5 has 2 beads. Column 3 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 5, the one that just finished, with Column 3.

DDT05 Cockroach Pig Entry #1

This bead is at Row 2. Column 1 has a bead at Row 2 too → red (=).

  1. Column 4 goes down to Row 2, so use Rule 2: look 3 columns back, at Column 1.
  2. Column 1 has a bead at Row 2 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.

Key Facts & Table Specifications

DDT05 8-Deck Hand Distribution
70 Hands (34 Banker / 29 Player / 7 Tie)

Seed 204305 opening column signature: C1:2B · C2:2P · C3:2B · C4:2P · C5:2B · C6:2P · C7:2B · C8:2P.

DDT05 Big Road Span & Max Streaks
Max 4B / Max 4P Across 30 Logical Cols (30 Display Cols)

In a 2-by-2 twin run, the first bead of each pair triggers Rule 1 at Row 1 (comparing prior depth 2 against depth 2) and the second bead triggers Rule 2 Case 1 at Row 2.

DDT05 Big Eye Boy Rule Breakdown
60 Marks (30R / 30B · 50.0% Red across 24 Display Cols)

Rule 1: 28 marks · Rule 2 Case 1: 0 · Case 2: 0 · Case 3: 32.

DDT05 Small Road & Cockroach Pig Tally
SR: 31R/27B (53.4% Red) · CP: 44R/12B (78.6% Red)

When a column finally extends to a third bead at Row 3, it steps exactly one row past the reference column's depth-2 stop point, producing a textbook Rule 2 Case 2 Blue (≠) break.

DDT05 DERIVED-ROAD & CUT-CARD PROBE

DDT05 Lookback Split (30R/30B BEB · 31R/27B SR · 44R/12B CP)

When a column finally extends to a third bead at Row 3, it steps exactly one row past the reference column's depth-2 stop point, producing a textbook Rule 2 Case 2 Blue (≠) break. Across DDT05, Big Eye Boy prints 30 Red (50.0%) and 30 Blue marks, Small Road prints 31 Red (53.4%) and 27 Blue marks, and Cockroach Pig prints 44 Red (78.6%) and 12 Blue marks.

At the DDT05 cut card after Hand #70, probing Hand #71 via getNextRoadPredictions() yields Banker → BEB BLUE / SR RED / CP BLUE and Player → BEB RED / SR BLUE / CP RED for DDT05.

Table Reality Check

Myth vs. Truth

MythThe second bead of each pair in DDT05 marks Blue because the 2-bead column is about to end.
TruthAt Row 2 in DDT05, the reference column also has a bead at Row 2, so Rule 2 Case 1 marks Red (=); a break only appears if a column stops at 1 or extends to Row 3.
