[split] Does Voynichese evolve from A to B?

[nablator]

I understand that they detect changes in the grammar and/or the lexicon, especially at the beginnig, that are consistent with its Author perfecting the language based on his increased experience in using it.  Isn't that so ?

I haven't read and checked all the presented evidence yet, and compared with the VMS, only the "mirrored C with mirrored c-diacritic", neither have you, so why argue before we know what's going on?

From what I've seen in a quick check, and posted earlier in this thread, the behavior of "mirrored C with mirrored c-diacritic" (hardly any in about the first half of the reordered Rohonc codex, then many in the 2nd half) is not much different from ed in the VMS (hardly any in Currier-A pages, then many in Currier-B pages).
