How fast could a scribe write a Voynich like text?

[dexdex]

- if it was done on a hurry to deliver the ready product on some tight deadline then it would take few weeks to few months

See, this assesment is interesting to me. I could see some scribe bragging about having a book and then someone offering to buy it and the scribe making something up in a month. But if it would take half a year even in that scenario, surely that makes the scenario much less plausible, no?

There is of course no upper bound on how long it would have taken, I agree  But I am wondering if we can put an educated lower bound on the time for each of these scenarios.

My guess is someone adept at writing + writing plausibly looking gibberish (like the gaskell & bowern experiments) could knock it out under a month. But I may be entirely off base since I am unfamiliar with scribal speeds in late medieval times, hence my question. I am wondering if such questions have even ever actually been investigated beyond the standard scenario of 'a scribe copying faithfully'.

It would be good to know how much time the participants of the g&b experiment had for the creation of their document. Does anyone know? If it's in the article I missed it.

Personally I can knock out pages of freely written handwritten text in an hour, but I am not using a quill pen or ink. If I were to make a faithful copy, I would need orders of magnitude more time. That probably held true even in the past, but to what extent do the supplies limit writing speed, and hence the magnitude of the difference?
