RP(approval) would be approval-completed Condorcet that restricts itself to 
members of the Smith set.

SSD(approval) would be approval-completed Condorcet that restricts itself 
to members of the Schwartz set.

"While there is no CW, eliminate the Approval loser" would always elect a 
member of the Smith set, but it would not, strictly speaking, be approval 
completed Condorcet, since it could elect someone who is neither the 
approval winner nor the Condorcet winner.

I remember Forest having another idea about ACC refinement recently, but I 
never had a chance to look at it seriously.

What if B's published ballot was B>A>D>C?
