Trying again and adding more...
A neat measure of neatness,

I agree, counting the number of tokens (especially focusing on the string used
to define the verb) is not particularly productive, nt=. # @: ;: @: lr @: <

Counting the number of structural components is, in my opinion, better as a
measure of the complexity of (honest) fixed tacit verbs,
