About word length distribution

[oshfdk]

This seems very unlikely. If you examine the writing in the manuscript you will notice that there is a fluency to it. There doesn't appear to be much stop-start in the text. The words in each line broadly keep to the same baseline. The writer isn't putting the pen down after each word to roll dice ( nor for that matter to consult any book cypher or perform any mathematical computation to determine what the next word should be ). In my opinion the writing of each page was done in one sitting in one uninterrupted rush of effort.

I'm not sure how you determined that. 

How about an experiment? I left my quills when moving, but when I get a new one, I will create a few inscriptions, some of them in one go, some of them with a pause after each word, and some of them even writing words non sequentially. My expectation is no-one will be able to tell them apart after they dry out. I'm a complete amateur with only a little experience with quills, but as far as my experience goes, writing with a quill will cause somewhat unpredictable ink density, but this depends on the writing style and how often and how deep you dip the quill into the ink, which in turn depends on the viscosity of the ink, the quality and size of the quill and one's technique. All other possible effects can be masked by this basic irregularity. 

As for keeping the baseline, I think this is a basic skill of a professional scribe. And, frankly, the baselines in the Voynich MS do get wobbly quite often. On the other hand, the writing itself is so tiny, this is not something unexpected. I did an experiment a few weeks ago, when I tried writing Voynichese to scale (just with a pencil). I really struggled initially, because most strokes are 1-2 mm long. I think the majority of people studying the manuscript imagine the writing about 2-3 times larger than it actually is.
