How fast could a scribe write a Voynich like text?

[ReneZ]

Undoubtedly there is plenty of historical evidence about the speed of professional scribes, but I don't have this.
My feeling is that the 'committing to paper' part is perhaps not the largest part of the entire creation process.

Also, if the MS is a fair copy, one has to include the time both of creating the draft and creating the copy.
