I am looking at this without looking at MAM.

In other words, of the bottom two alternatives on the most popular list, the one that is ranked ahead of the other on more ballots than not is kept, and the other is eliminated.  This elimination rule is repeatedly applied among the remaining alternatives until only one candidate (the method winner) remains.

Looking much like Condorcet.  From there we know that cycles can occur, 
needing more thought here.

Starts out looking good but, how many lists might there be with half a 
dozen candidates?
      What would this quantity do to the voting machine?
      How much might this confuse the voter looking for an acceptable list?

Sounds like as much trouble as Condorcet and in counting complexity, 
though doable with present voting machines - provided they can tolerable 
the number of choices.
