Let me just add one more point, which may be obvious. I had a hunch that 
some some strange results could occur with MMPO. Why? Because it chooses 
the winner based solely on the number of votes *against* each candidate. 
It does not even consider the number of votes *for* the candidates. 
Something seemed seriously out of balance. Hence the case you cite 
above, in which a candidate wins with only 4 non-last-place votes out of 
100 votes. Oh well, it was fun while it lasted!
