Is this just the Instant Run-off version of STV that you're talking about that pays no attention to who you ranked below top? Also your example here - http://rangevoting.org/PRcond.html - would that be resolved under any form of STV in existence?

RRV incentivizes exaggerating in your vote to max and min scores; but it also de-incentivizes that because if you exaggerate then your vote gets de-weighted more when your guy wins a seat. So the net result is probably that you are incentivized to exaggerate on candidates whose winning chances seem poor, but to try to "free ride" for candidates that seem sure-thing winners by dishonestly not giving them high scores. With STV, a big flaw is that it pays no attention to anybody you ranked below top. If you ranked Bush>Gore>>>Hitler, it pays no attention to the "Gore>>>Hitler" part of your vote, until after Bush is elected. And basically, any party voter-bloc which ranks Green-party candidates above all others, will have zero effect on non-Green winners until after the last Green has won, then some small fraction of "leftover" green power will be able to exert some (tiny and varying with the size of the leftover in a rather random-seeming way) effect. This ignoring, seems a very serious flaw of STV, that is not present with RRV. -- Warren D.
