About word length distribution

[dashstofsk]

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.
