[EM] Forest: MAMD

MMPO has several big advantages:

1. The unmatched brevity of its definition
2. Its full-rankings flexibility, which allows the full sincere-expressivity benefit of AERLO
3. Its ability to elect unfavorite middle CWS better than do most or all of the conditional methods

(Of course, though, in fairness to the conditional methods, the election of an unfavorite CW would be seen by most people as a bad-example)

A modification of MMPO that would avoid Kevin's MMPO bad-example, without gaining some other 
un-plurality-like outcome that would bother people, without losing FBC or ABE-success, and without
significant added complication or wording--that would be a good thing to find.

Tell me if this is MaxAssentMinDissent (MAMD):

MMPO, except that each ballot that doesn't rank x is counted as voting x over himself, which is treated
as any other pairwise opposition in the MMPO count

[end of definition of MAMD?]

Because MAMD has just been posted, I haven't yet had the opportunity to evaluate it. Tell anything
you find out about MAMD and the matters discussed above.

In your post, you mentioned symmetric completion, at bottom, and everywhere but top. That isn't used in
MAMD, is it?

MMPO with symmetric completion at bottom, while avoiding Kevin's bad-example, also sometimes loses
MMPO's ABE-success:

60: A>B
55: B
100: C

B wins.

Maybe MAMD is what can make MMPO one of the best, criticism-invulnerable, FBC/ABE methods.
