The flaw in STV-CLE I see is that the candidate elimination heuristics is based in a majoritarian criterion in a PR method. I think that a good heuristic to eliminate a candidate should be based a PR quota, like Newland-Britton. Some months ago I desgined the "Bucklin elimination STV" (I don't have a definite name for it). When no candidate reaches a quota, then later preferences are added until some candidadate reaches the quota. But, instead of this candidate is considered elected, the candidate with the least sum is eliminated. Some examples with this method has generated good outcomes. ________________________________ Diego Santos
