Assumptions baked into the VMS carbon dating

[eggyk]

Also it seems that some parts of VM could be inspired by De ingeneis by Taccola (You are not allowed to view links. Register or Login to view.). It you accept it, it sets VM past 1433 and makes 1385 impossible.

Well, I don't agree that if certain parts are post 1433, other sections couldn't be from 1385. Why does one section have to date an entire manuscript? As the example in the OP shows, just because the illustrations within that manuscript are clearly late 15th century does not date the text in the manuscript, which was written far earlier.

And what do you exactly need the extended creation period for? Do you have any hypothesis that requires it?

I don't require it for any theory, and I am not stating any of this to push any theory. If the reality is that the 1404-1435 dating range is potentially incorrect, that should be considered for all theories. 

I don’t really know much about this topic. As I understand it, the period determined by radiocarbon dating is usually more or less accurate — that is, if a parchment is dated to around 1350, it’s unlikely to have been written in 1300 or 1400, but I could be wrong.

As I stated, I am not disputing the individual results for each page. I am disputing that their results are combined as if they are the same object. Here is the dating for folio 68:
