A family of grammars for Voynichese

[ReneZ]

So far I have excluded {ith} {ikh} {iph} {ifh} from the set of valid elements.  

However there are 70 words (tokens) with those combinations in the whole parags text, out of more that 30'000 tokens.  Is that significant?  Contrast that with 1622 occurrences of {cth} {ckh} {cph} {cfh}. 

Maybe I should accept those 'i' variants too (and treat them too as platform gallows, CMC class "H").

On the other hand here are only 4 occurrences of {ih}; contrast with 9362 of {ch}.

This may be a clue that {ith} {ikh} {iph} {ifh} are instances of {cth} {ckh} {cph} {cfh} that were mangled by the Scribe/Retracer/Transcriber. So maybe we should just "error-correct" them as such.

Your counts correspond reasonably well with those in this document: You are not allowed to view links. Register or Login to view.
for the three most complete transliterations.

At this point, I don't see any way how we can conlude that things like ith / iTh are meaningfully different from cth / cTh or not. If we found that they strongly depend on the scribal hand, then that would be an indication, but I do not think that that is the case.

Failing that, we can just record the differences, and then decide when doing stats. The problem with that, of course, is that one quickly runs into many different scenarios based on different combinations of 'choices' to be made, to the point where it becomes totally unpractical.
