WV is "winning votes". Say the method in question works upon variables 
d[x,y], and the Condorcet matrix is c[x,y] for some pair x,y of candidates.

Then, WV defines:
   d[x,y] = c[x,y] if c[x,y] > c[y,x], otherwise 0.
and Margins defines:
   d[x,y] = max(0, c[x,y] - c[y,x]).

"Pairwise Opposition", the PO in MMPO, just defines d[x,y] = c[x,y].

There are other ways of defining d as well, but those are the most 
common (and wv and margins much more common than PO).
