[Conference] Voynich Manuscript Day 2025 Recording on YouTube

I wondered the same, Bluetoes. Again, I think there is no definitive answer. It might perhaps be useful to think of a certain style to be "on its way out" eventually. You may still have some older scribes who write like they're used to, but others will have learned differently or adapted. Either way, handwriting styles are best thought of as belonging to a long period of time. But at some point you can say "now it becomes rare". 

Going by our current samples, the peak of the style appears to coincide with the radiocarbon dating period. And perhaps earlier too, but I didn't check many earlier documents. So we have a period of half a century or more, that seriously tapers as we move into the second half of the 15th century.

Again, though, I'd be more than okay with any additional samples changing our view on location and time.
