DR257 pairs 3-2-3-2 Depth Alternation (Big Road depths [3, 2, 3, 2] comparing m=1 vs m=2 lookbacks) with Question-Driven Modality (Socratic Inquiry): learners verify For m=1, d_3=3 != d_2=2 (Blue); for m=2, d_3=3 == d_1=3 (Red), master Lookback Divergence: Big Eye Boy Blue vs Small Road Red, and eliminate assuming all three derived roads must show the same color on a hand.
DR257 drill board (BBPPBBBBPPBPPPBPPPBBBP): 10 Big Road columns, 19 Big Eye Boy, 17 Small Road, and 13 Cockroach Pig marks.
This bead is at Row 2. Column 2 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 2 stopped exactly one row above this bead.
This bead is at Row 4. Column 1 stopped at Row 2, more than one row above → 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.
Column 5 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).
Common table reading watchout: Comparing the wrong columns. Compare Column 5, the one that just finished, with Column 2.
Big Road depths [3, 2, 3, 2] comparing m=1 vs m=2 lookbacks
Lookback Divergence: Big Eye Boy Blue vs Small Road Red
For m=1, d_3=3 != d_2=2 (Blue); for m=2, d_3=3 == d_1=3 (Red)
Assuming all three derived roads must show the same color on a hand
Verify why Small Road (m=2) marks red while Big Eye Boy (m=1) marks blue by answering three sequential checkpoints: row position, lookback m, and parity
Under Question-Driven Socratic Drill (DR257), 3-2-3-2 Depth Alternation isolates Big Road depths [3, 2, 3, 2] comparing m=1 vs m=2 lookbacks and For m=1, d_3=3 != d_2=2 (Blue); for m=2, d_3=3 == d_1=3 (Red), turning BBPPBBBBP-PBPPPBPPP into a hands-on 19-mark verification.
Applying Lookback Divergence: Big Eye Boy Blue vs Small Road Red in DR257, This bead is at Row 2. Column 2 has a bead at Row 2 too → red (=). Those 17 Small Road dots and 13 Cockroach Pig slashes accompany Big Road depths [3, 2, 3, 2] comparing m=1 vs m=2 lookbacks during answering three sequential checkpoints: row position, lookback m, and parity.
