Are marginalia clues?

[ololololo]

With the exception of the inscriptions in the Zodiac, I believe it is possible that the marginalia on f17r, You are not allowed to view links. Register or Login to view. (specifically "der musdel"), and You are not allowed to view links. Register or Login to view. were added by someone who understood the manuscript. ... What do you think?

As for f116v, You are not allowed to view links.

My guess is that the same explanation holds for the non-Voynichese writing at the top of f17r, although the extent, date, and consequences of the water stain there are much less certain.  

I have no theory yet for the non-Vonichese writing at the bottom of f66r.

In fact, it doesn't seem very logical for two reasons:
1). It is unclear why the author had to change the letters during the "reconstruction". If you had a book in conventional Greek, but the inscription on the last page was erased, you wouldn't try to reconstruct the erased text by changing Greek letters to Latin letters, would you? As for the "clumsy cleaner", he hardly had any problems with development, and he would have noticed that the result was some kind of nonsense. 
2). For some reason, the same letter rearrangement did not occur on the f103r. Apparently, the "ketchup" stain was left by a more decent person
