alternating patterns

[Anton]

Last but not least, one should mind the possibility of shuffling. Indeed, there are indications that the text might have been put down in several passes, which, among other things, suggests shuffling.

Is there a thread here or link with more info about that?  I haven't seen that before (I'm relatively new to Voynich studies).

Yes, there is, although it might have been not a dedicated thread. I remember Wladimir and/or JKP even provided some screenshots. I guess this can be searched by the key phrases "several passes" or "more than one pass", since those are phrases which I use when I express myself on this matter in Elglish, and I was a participant to that discussion.
