Actually it does satisfy SFC. That's fine too, I guess? So really, the method is a more ranking-sensitive version of MAMPO.

Suppose that SFC disqualifies B due to A. (There's an A>B majority, but no majorities over A.) That means A's IA-MPO is positive. B's IA-MPO could be positive as well. But his MPO is >50% while A's is less. So, B won't win.
