I do not see such a big difference; IMHO, Currier got that impression
only because he looked at two parts of the manuscript (Herbal A and B)
which seem to be at opposite ends of what is better described as a
spectrum.
According to the only handwriting expert report we have, the VMS
script it is in one hand throughout. Word frequency plots like those
by Rene and myself here show fairly clear differences in word
frequency between sections, but many of the words do occur throughout
the book -- something that is not usually seen with different
languages, even closely related ones like Spanish and Portuguese.
