A more particular mutual-majority & weaker MMC

Lately I’ve been referring to a more particular mutual-majority than the
solid-coalition:

A top-mutual-majority is a mutual majority, a solid coalition, for which
the set of candidates that they all prefer to everyone else consists of the
set containing the favorite candidate of each of them.

I guess, then, any method meeting MMC would meet top-MMC, but not
vice-versa, which, then, means top-MMC is weaker

I’ve lately been using “mutual-majority” to mean “top-mutual-majority”…

…when I say that Hare always chooses from a mutual-majority when there is
one.

According to Electowiki, Hare also always chooses from a solid coalition
when there is one.

Burlington, Alaska & many polls suggest that our electorate, the
progressives are the top-mutual-majority.

…& therefore can’t lose in Hare.

One way to say it:

If wv would make a good choice when it elects the CW, then we have
confidence in the CW’s  voters, the median voters.

Then surely we have confidence in their 2nd-choice too.. the direction in
which they send the win if the CW is eliminated.

As I said, there’s good reason to believe the win will be sent in the
progressive direction.

…especially relevant given wv’s prohibitive count-task, which endangers
count-fraud security.

I mentioned tha Hare’s handcount doesn’t require any more votecounting than
that of Approval…making handcount-audit JGA’s feasible.

But Approval still has a less complicated count, making it better for
count-fraud detection & prevention.

Approval is my favorite for that reason, & for its minimalness, & easiest
definition, explanation, proposal, enactment, implementation (zero-cost), &
administration.

MIchael, to make sure I understand your definition, could you give an
example of a method that meets top-MMC and not MMC and an example election
in which it does?
