[EM] Fwd: XA

[Michael Ossipoff]

So XA fails Participation. So what? Participation is just one of those
"could-look-bad" criteria, like the Plurality Criterion.

We all know that if you want anything that Approval & Score don't offer,
then you have to pay for it, with "could-look-bad" criterion-failures.

And the more you want, the more "could-look-bad" you have to accept.

Plain MMPO is tops in important strategy criteria and properties, and so,
it has the most could-look-bad.
...which has been shown to not significantly wrong anyone or be a genuine
problem.

As I've been saying, improvements on Approval are mostly or entirely
illusory.

wv strategy could be some strategy improvement, but it's a bit
questionable. But, in addition to FBC & wv strategy, Plain MMPO offers full
reliable Weak CD compliance.  (Its failure of strong CD is mitigated by its
wv strategy's burial-deterrence.).

It's difficult to improve on Approval, but, if any method can, in some
meaningful way, Plain MMPO is the method that best qualifies for that claim.

You get what you pay for.
