Strong evidence of a structured four-phase system in the Voynich Manuscript

[pfeaster]

It looks like while I've been trying to wrap my head around the earlier hypothesis based on four phases, it may have been superseded by a new hypothesis based on three macroblocks.

Still, is this a fair layperson's summary of the earlier hypothesis, stripped of the methodology used to develop it? --> 

"The text of the Voynich Manuscript cycles repeatedly through four distinct phases with identifiable features, producing a kind of large-scale textual rhythm.  Shuffling the folios out of order destroys this cycle, which thus appears to be a real larger-scale structural pattern."

After reading through the thread (but not checking out the Github repo, which has been offline), I'm still unclear on the period of this proposed cycle.  There's talk of identifying the phases of individual "folios," but parts of the discussion make me think this may really refer to pages (such as f1r) rather than to literal folios (such as f1, including You are not allowed to view links. Register or Login to view. and f1v).  And then:

These cycles show up between folios and inside them, and they break when shuffled. So it’s not just the order — it’s baked into the content.

All this leaves me uncertain as to the cycle's period: is there one phase per page, or per folio, or can pages contain multiple phases, or....?

Also, as to the shuffling: was this carried out on individual pages (f1r, f1v, f2r, f2v, f3r, etc.), or whole folios (f1, f2, f3, f4, f5), or bifolios (i.e., keeping the bifolios themselves intact, but organizing and nesting them differently)?  I wonder whether this makes a difference, bearing in mind Oshfdk's suggestion:

For example, there can be differences in how a page was structured based on where in a quire it appears, which could produce cyclical features.

Urtx13 wrote (possibly in reply to that last quotation):

We also checked within individual folios, to rule out recto/verso or binding effects. The structure persists locally.

I'm curious what form this last experiment took.  What specifically was ruled out, and what patterning persisted at what local level?
