Similarity of Voynichese glyphs according to their immediate statistical environment

[Mauro]

I tested if 'te' is similar to 'p' and 'ke' to 'f' ('te' and 'ke' were the only substitutions made), on Herbal A. They don't look similar, average distances are rather high (distance_following and distance_previous are high too). 'te' and 'ke', instead, strongly resemble... themselves, and are rather distant from any other character (in Herbal A, at least)
