Condorcet method, I could devise another one where the winner pairwise
beats the winner of that one more often than vice versa. Someone could have
a method they call BEST METHOD. Then all I have to do is say under my new
method, elect the Condorcet winner if there is one. If there isn't, elect a
candidate that pairwise beats the winner using BEST METHOD, if there is one
(pick at random if there's more than one). Otherwise just pick the same
winner as BEST METHOD.


Sorry, no good.

MAM's winner doesn't beat Schulze's winner in that contrived manner.

The MAM winner beats the Schulze winner for a simple, obvious reason:

MAM doesn't disregard a defeat unnecessarily or without obvious, compelling
justification. Schulze does.

Look at the brief, simple, natural & obvious MAM definition that I posted.
