I brought this up in late May of 2004. As I recall, the idea didn't
meet
with much support. I agree that runoffs are expensive and ideally
shouldn't be necessary, but there may be situations where the benefits
outweigh the costs. Once I designed cardinal pairwise, which seems to
have
fairly strong anti-strategic properties with a single round, I stopped
talking about the two round system. Still, perhaps the idea should be
kept
afloat to some degree, e.g. given a name and an electowiki page. I also
proposed a procedure in December 2003 which is similar but with no
fixed
limit on the number of rounds... I consider this one to be excellent
in a
small group scenario, but impractical when the number of voters is very
large.
my best,
James

Yes, I think the idea of two round of multiple round Condorcet should
be kept floating. The burden of additional rounds may not be a problem
in some settings. (If multiple rounds are not wanted, then just skip
this method proposal.) Another reason for keeping multiple round
Condorcet methods alive is educational. I think they nicely point out
some essential characteristics (strategy free vs. "strategical" parts)
of Condorcet methods. Yet another way of using multiple Condorcet
rounds is to use them as opinion polls. If some (not necessarily even a
small) group has access to quick computerised voting, it is no problem
to check every few minutes how people feel about certain
questions/options (it is also possible to have even a continuous
real-time opinion poll that displays the changes whenever someone
updates his/her previous ratings (some privacy protection can be added
if needed)). And when the timing seems to be right (=Condorcet winner
visible), the chairman can propose to make a decision.
