The gallows intrusion, the baseline jumps and multipass

[Anton]

More generally, even if the "alternating lines" hypothesis proves false (and it's easily checked by inspecting more folios), it's still likely that the vords above the intruding gallows were written after the vords containing the intruding gallows.

Respectively, if we manage to detect a pattern of one (or both) of these subsets of vords, that could be a huge leap forward.
