If I remember correctly Kevin Venzke's first post to this list was a geometric 
argument that 
the MMPO winner was apt to be closer to the voter median position in Approval 
than the 
Approval winner.  The scenario he had in mind was something like this

Scenario One:

26 A
24 A=C
24 B=C
26 B

The geometry was something like this:

AAAAAAAAAAAAAAAAAAAAAAAAABBBBBBBBBBBBBBBBBBBBBBBBB
_________________CCCCCCCCCCCCCCCCCCCCCCCC________________

It weemed pretty obvious that the MMPO winner C was more likely the true 
majority choice 
than than either of the tied approval winners A.or B.

Not long after that Kevin came up with his MMPO bad example:

Senario Two:

48 A
2 A=C
2 B=C
48 B.

The MMPO winner C lacked too much approval to be the real winner. Kevin took 
back his 
proposal, and went on the bigger and better things like trying to convince Juho 
that MinMax
(margins) was not an acceptable public proposal. either.

But as I mentioned in a recent posting MMPO with symmetric completion is the 
same as 
MinMax(margins), and by exempting the top rank or slot from the symmetric 
completion, we 
get a really nice compromise between MMPO and MinMax(margins), and what's more 
this 
version gives the "right" answer in both scenarios above.  Kevin was ever so 
close to 
proposing what I now call LRV "Least Resentment Voting" or more technically 
Bottom-
Symmetric-Completion MMPO.

In the first scenario above both A and B have max opposition of fifty, while 
the max opposition 
of C is 26 + 13 = 39, so C wins.

In the second scenario, A and B still have max opposition of 50 each, but now 
C's max 
opposition is  48 + 24 = 72, so C loses, to a tie betwen A and B.

Where is the cutoff where all three are tied?

Scenario Three:

34 A
17 A=C
17 B=C
34 B

In this scenario the max opposition (with the bottom symmetric completion rule 
in effect) is 
34+17 for A, 34+17 for B, and 34 +17 for C.

The second largest opposition to either A or B is 17+17=34, while the second 
largest 
opposition to C is still 34+17, so C loses the tied situation , and the winner 
is a toss up 
between A and B.
