Voynich text generator

[Emma May Smith]

Well, there are still plenty of instances of <o> in the Bio section, just not <od>, so this explanation does not really make sense to me.

We can't know for sure what his motivation was. Maybe there was no motivation and its just an switch. 
...

Then there is no explanation at all, is there? If we are happy that the writer just switched as and when he wanted, we can be equally happy saying that he just wrote out the whole manuscript according to his whims. There's not even any need to say he copied and altered words from recent lines, is there? You can't explain why words are structured how they are, or why certain character combinations appear and change throughout the text, or really anything.

The "Whimsical Author" hypothesis: he wrote the Voynich Manuscript because he wanted to, invented a new script because he felt like it, structured the words just because he could, and altered them without any motivation. It explains nothing, but at least we've finally solved the mystery!
