I'm not sure your IRV restricted to Smith set BUT do NOT eliminate the non-Smith candidates, is better than the pre-elimination.
Think you could make arguments either direction. But I guess this is an argument "for" BTR-IRV; with BTR-IRV you do not have to worry about that issue, since you get the same result either way. wds ---- election-methods mailing list - see http://electorama.com/em for list info
