MMPO2 sounds a lot like what I've called Ext-Minmax, but with pairwise 
opposition instead of wv or margins.

I originally devised of Ext-Minmax to resolve some tie problems while 
checking Smith,Minmax(margins) for mono-add-top failures - I didn't find 
any, but Kevin Venzke did.

What would the pairwise opposition equivalent of the Smith set be? Would 
it still be the Smith set - and would Smith,Ext-MMPO (to coin a term) 
pass mono-add-top?
