This bead is at Row 4. Column 5 stopped at Row 1, more than one row above → red (=).
- Column 8 goes down to Row 4, so use Rule 2: look 3 columns back, at Column 5.
- Column 5 stopped at Row 1, more than one row above → red (=).
Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 5 stopped exactly one row above this bead.
