I just wanted to respond to Craig before asking about Borda, Nanson, and
"Crosscut" methods in my next post (I'm going to call "my" method the
Crosscut method -- at least until I find out who was the original inventor
-- since it calculates from the top down and from the bottom up, then
tie-breaks any discrepancies)

Sounds like an IRV variation? AN IRV VARIATION?!?!? You take that back!
Hehehe, just kidding. I like IRV better than Plurality, but Approval better
than IRV, and Condorcet-winner/Smith set winner methods best of all.
Condorcet-completion methods and methods like Nanson's where the winner
comes from the Smith set are my favorites, and if IRV fans would support
such a method, I'd support *them*. Even if the completion method was wacky,
the fact the method would choose the "best" candidate if possible ("best"
in my opinion, I should say), and from the set of best candidates if no
single best candidate can be found, would be enough for me to jump on the
bandwagon. Any such method is so much better than Plurality that arguing
about it would be like arguing what color paint is best for a race car --
is red faster than yellow? (On the other hand, it *is* a heck of a lot more
fun to argue than paint colors.)
Is the "Crosscut" method better than other completion methods? If it is,
it's a difference probably measured in fractions of a percentage point or
by the lack of a rare, illogical outcome. If it were worse than other
methods, it would almost certainly be by the same fractions of a percentage
point or adding a rare, illogical outcome. The only strong argument I have
at this point is that it's easier for me to visualize (grin).
