I had a simpler example in mind:

Three teams in a round robin tournament compile the following scores:

A beats B four to three, B beats C two to one, and A beats C two to one.

A is the Condorcet winner while C is not only the Condorcet loser, but
also the method winner under this variant of MinMax, since this team never
gave up more than one point per game, while each of the other teams had at
least two points scored against it in one game or another.
