[Conference] Voynich conference - Some questions

[hermesj]

Dear Torsten,
I think I chose a misleading term with "randomly selected". After all, a true random process was also difficult to realise in the Middle Ages. What I mean is that the writer can choose any cipher from a number of different words to replace a single letter. This human choice is difficult to simulate (Even more difficult than the autocopying process, which you managed well of course).
Did the codebook consist only of a series of loose pages? Were there only a few of them on the table at any time of the writing process? Were they (partly) replaced for every new page / folio / quire? Were some used over and over again (in the same order), etc.? From these possible selection processes, I think one can also explain the differences between Currier A and B, by simply selecting other (in the Trithemian system columns of) cipher words. 
It is still important for me to say that I am not claiming that the methodology I put into play is actually responsible for the Voynich Manuscript. My point is only to discuss whether it is merely improbable or impossible.
