One statement I left out of the CD definition was that the C voters vote C over A & B. But I think that's understood. Referring to that definition: We can call the U/P ratings top, bottom & middle. A middle rating just means neither a disqualification vote nor a preference vote. Say the C voters bottom vote A & B. Say the A & B voters bottom-vote C. Say the A voters middle-rate B. ...& the B voters bottom-vote A. All of that is consistent with CD's premise. B is the only candidate not bottom voted (disqualified) by a majority. B wins. CD's requirement isn't met. Michael Ossipoff

Mike, Thanks for that explanation. I now see that I erred when I claimed that U/P meets CD and therefore has some justification versus some other 3-slot FBC methods (such as IBIFA, MTA, MCA).
