On the cap from last bread I see 5:5 is forward and 11:11 is backwards re: mirror/clock direction.
He explains (in order) 5:5 then 11:11 (followed by positive integer addition to neg integer and vice versa) Also identifies prim_ & _sec (primary comes before "blank" and secondary comes after "blank": blanks being markers/etc). Also shows numbers with them:
8:26:31 w/5:5
7:24:28 w/11:11
Very clear pattern: (change from first digits to second set)
8:26:31
7:24:28
Is -1:-2:-3 (countdown)
Just some thoughts.
