Mapping between Currier A and B

[ReneZ]

Hi Marco, yes, the observation that new words all of a sudden become very frequent is something that requires a better explanation.
This is one of those cases where it is not difficult to come up with quite a number of possibillities, especially taking into account combinations, but it is of course extremely difficult to judge how 'likely' any of these is.

Some examples would be
- Change of dialect by itself
- Change of dialect in combination with some encoding
- Change of scribe
- Change of handwriting in a source document in combination with some encoding
- Minor change of a rule in combination with some encoding
- They are null words

A numbering system in combination with a change of dialect could result in the observed effect.

The strong impression I have is the the evolution in the direction A -> B seems easier to explain than in the other direction.
