I don't agree that this is a strange interpretation, or that defeat strength is not the idea of RAV. When I (re)proposed this method in November, you and I spoke primarily in terms of defeat strength, and already in my initial message I noted the method was the same as electing the least-approved candidate who beats everyone with greater approval: http://listserver.dreamhost.com/pipermail/election-methods-electorama.com/2004-November/014115.html It seems to me that you were quite critical of RAV/DMC and I still don't know why you changed your mind: http://listserver.dreamhost.com/pipermail/election-methods-electorama.com/2004-November/014127.html http://listserver.dreamhost.com/pipermail/election-methods-electorama.com/2004-November/014148.html You wrote: "Then you came up with the topic of how to measure defeat strength best without having to count all winning votes, and suggested to use approval scores. I pointed out that when using approval of A to measure the strength of A>B, you count some people towards that strength who actually prefer B to A, and that this possibility will be counter-productive when trying to convince people to go voting." I guess you and Russ think that if we "interpret away" defeat strengths, then this problem disappears??
