That's a simple and interesting method. I can see the mechanism is to
remove control of the *strength* of the Y:Z win from the X voters. Then
measuring strength as FPs is fairly likely to correctly discard the win
of the least important candidate.

I guess that anything else that does something similar would have a
similar advantage.
