I know I'm foolishly ignoring the wise advice John Camp gave in his
post script, but

Are you sure it's such a tidy, fundamental structural property? I
think the following should have just as much right to invariance:

If touches A and B are touches of three or more leads of a single
method, modifying either by replacing one lead, not the first or last,
with a different method results in the same number of changes of
method for touch A as for touch B.

By your counting, that is a false statement.

And yet, once we've introduced one lead of a different method, further
modifications (assuming the same contiguity with existing changes of
method and/or same first and last leads) do result in the addition of
the same number of com.

Easy enough with Möbius Surprise Major.
