You said that SARA does particularly well by VSE.

But VSE is: (winner's SU)/(average SU among candidates)

...where SU is social utility.

...which is some constant minus BR.

But I've just told why BR is no good as a measure of the rightness or
goodness of an outcome.

Take a dollar from a homeless man and give it to a billionaire? That's a
negative change, because changes in greater disutilities are more important

>    Default is abstain. Candidates get 2 points for each percent of "support"
>    and 1 point for each percent of "accept", for a total of 0-200 points.*
>       - *"Support" the best candidates (perhaps a quarter of them),
>       "reject" the worst (perhaps half of them). "Accept" and "abstain" are for
>       the ones in the high middle range. For those, "accept" if you want to help
>       them beat somebody worse, and "abstain" if you could live with them but are
>       hoping for somebody better.*
>    2. *Eliminate any candidates rejected by over 50%, unless that leaves
>    no candidates with over 50 points.*
>       - *If possible, the winner shouldn't be somebody opposed by a
>       majority. But this shouldn't end up defaulting to a candidate who couldn't
>       at least get accepted by over 1/2 or supported by over 1/4 (as in, a
>       majority subfaction of a divided majority, such as Nashville voters in the
>       example below).*
>    3. *Highest points wins. In case of a tie, fewest rejections wins.*
>       - *This finds the candidate with the widest and deepest support.*

>> Support Accept Reject Abstain voting works as follows:

>>    - Call a candidate "acceptable" if they are rejected by 50% or less

>>    eliminate all who aren't.
>>    - Give remaining candidates 2 points for each "support", 1 point for
>>    each "accept", and half a point for each "abstain". Highest points wins.
>> This moves a bit away from the Bucklin roots of MAS, but it further
>> reduces the instability of cooperation in a CD scenario.
