Balinski & Laraki have apparently done quite a bit of work on range voting or something very similar, including a book (?). However, they advocate use of the MEDIAN rather than the AVERAGE with a certain tie-breaking scheme. I've been trying to speak with Balinski for some time but he ignored me until just now. Anyway, this website summarizes what B&L have done. I translated it into English: http://RangeVoting.org/BalinskiL.html wds ---- election-methods mailing list - see http://electorama.com/em for list info
