What would the values be to acheive vanilla book size behavior?

I see the settings under “book-size” and “item-validation” which control max book sizes; what would the values need to be there to mimic the behavior in vanilla? Right now I have those settings configured with the paper default, but I want to know what they’d have to be to match my vanilla testing server.

Thanks!

For book size, iirc, it is 256 characters per page and since 1.14+, 100 pages per book. Or ~25,600 characters total.
