So I take it you are assuming a zero-info situation. Just about any other situation would require that A be predicted to have some chance of winning, which doesn't seem very realistic. IIRC my simulations did find that as the number of candidates increased, zero-info Approval did worse in comparison to Schulze. With five candidates it was a little bit better than Schulze. I consider myself possibly a "fanatical advocate of Approval," but I don't feel that SU performance is an important argument for it. Kevin Venzke [EMAIL PROTECTED] Yahoo!
