The oddities of the bigram "ed"

[Dunsel]

Well, bigram statistics show the behaviour of bigrams.

Comparisons with English (or Latin etc) may not be relevant because the Voynich MS text behaves in a very different way from these natural languages.

Their frequency may depend on the subject matter but it remains to be seen to what extent.

Should the Herbal-A and Herbal-B pages be about the same subject matter?
Their bigram statistics are wildly different, so we have a strong statistical observation that requires an explanation.

Bigram statistics are not the only thing. They are a piece of the puzzle.

Again, making me think.
