I don't see any obvious way of improving on Craig's idea for modifying open list PR in the context of many winner elections. For two or three winners, I think that PAV (Proportional Approval Voting) is the best. Around half a dozen winners, perhaps some version of STV would be most practical. With a dozen or more winners some form of list PR seems the most practical to me, though my intuition isn't as far advanced as Craig's on this. Forest
