	I'll agree that RAV has a significantly shorter definition than AWP. On
the other hand, AWP has greater resistance to strategy. The relative
importance of these two factors should be decided on a case-by-case basis,
that is, in a particular electorate considering a change to a new voting
system.
	Thus, rather than saying that one method or the other is useless, I
suggest that we should direct our discussion towards clarifying the
relative pros and cons of the different systems. Relevant questions are
grouped into at least two categories, i.e. strategy/technical merit and
explainability:
	Strategy/technical merit... Is AWP more strategy-resistant than RAV/DMC?
How strategically vulnerable is RAV/DMC? How strategically vulnerable is
AWP? What is the likelihood that strategic vulnerability in RAV/DMC will
lead to abuse, or push voters into making extensive use of compromising
counterstrategy? When one takes its strategic vulnerabilities, which
systems is RAV/DMC technically preferable to? (E.g. plurality? runoff?
IRV? CWO-IRV? margins? WV?) Likewise, which systems is AWP technically
preferable to? (By "technically preferable", I mean preferable from a
standpoint that is not sensitive to factors like explainability.)
	Explainability... Is RAV/DMC easier to explain than AWP? What is the
simplest way to explain RAV/DMC? What is the simplest way to explain AWP?
In what kinds of electorates might RAV/DMC be able to gain public
acceptance? In what kinds of electorates might AWP be able to gain public
acceptance?
	I suggest that we should address these separate question groups in
separate messages and threads.

my best,
James
