Yes. It's instructive to see what PR criterion AT-TV satisfies, and what RRV satisfies. The standard Droop criterion, if I'm not mistaken, is: If a group of N droop quotas of voters votes a set of >N candidates above all other candidates, then at least N candidates from that set must win. The AT-TV version would be: If a group of N droop quotas of voters votes a set of >N candidates at or above a given rating, and all other candidates below that rating, then at least N candidates from that set will win. The RRV version... well, I'm not sure, but my guess is that it would be something like: If a group of N droop quotas of voters votes a set of >N candidates each with at least N times the rating of any candidate outside that set, then at least N candidates from that set must win. Note that these are successively weaker criteria on the systems; that is, the coordination of a given party must be successively stronger to ensure PR for that party. Purely on a subjective level, I think that AT-TV criterion is about right, and that the RRV one is too weak. JQ
