Mapping between Currier A and B

[nablator]

This transition does not have to mean that words are actually being modified. It could be a shift of frequency.

True. Also the shift in frequencies shows that the A to B phenomenon is not unique, it is only the most visible. There are other shifts, at various scales, that need an explanation as well. It is not as if the settings or parameters, whatever they are, only get changed once, or evolve gradually between A and B.

It is a big leap of faith to expect a straightforward mapping between A and B. Perhaps we should question the assumptions behind it, i.e. the verbose cipher hypothesis.
