Discussion of "A possible generating algorithm of the Voynich manuscript"

[MarcoP]

I am beginning to wonder if one of the main features of the Voynich MS text is that it is really page-oriented, i.e. properties are quite page-dependent. This would fit with an encyclopedic work (like Pliny).

Comparing the most frequent words in VMS sections with those in different books (about different subjects) in Pliny, the problem with function-words pointed out by Torsten stands out.
I highlighted the words that appear among the 20 most frequent in all sections. In Pliny, these words are more numerous than in the VMS; they cluster near the top of the lists. 
As observed by Torsten, in the VMS the most frequent words in each section tend to be similar. 
In the Bio section, 7 of 20 words start by qok-, while in the Herbal A section none of the 20 does.
In Herbal A we find the group chol, chor, shol, shor.
An encoding like mod2 could map all function words into a few groups of similar words, but then we should see the same groups in all sections, while the 4 words listed above are frequent in Herbal A but not in the other two sections. 
The three most frequent words in the Bio section (shedy, chedy, qokaiin) add up to about 10% of the word tokens in the section, but they do not appear among the 20 most frequent words in Herbal A.

My impression is that, while it is possible that specific subjects are partially responsible for how similar words cluster together, this explanation is not sufficient. Aren't the differences between sections too large for a word-to-word mapping of a uniform language?
