I give the unranked B=C 1/2 vote each so that C 67 > B 33.  This makes B the 
margins winner thus making winning votes and margins results identical.  wv and 
margins become equivelent in the sense that one implies the other by giving equal 
rankings 1/2 vote each when completing incomplete ballots .  Can you show that 
margins will ever penalize a voter for complete rankings when equal ranking are 
counted 1/2 vote each?  If not, then I think your case for wv over margins is based 
on unjustified undercounting of equal rankings.
