I'm glad you think it's useful.

The problem was an egregious failure of Plurality:

n a
1 a=c
1 b=c
n b

When n>=1, C is elected, no matter how large n gets.

I say "probably" mostly because Approval exists.

Though I think it's quite possible that even the sincere preference
criteria you use are not adequately defined for some type of balloting
system that has not been foreseen. (Whether such systems would have value,
I doubt. But they could still exist.)

To my mind, that criteria can be applied unambiguously to all methods,
isn't the only concern. A system that merely applies to *most* methods
can be useful if it has other advantages.
