</p><p>sorry, but just on the surface this doesn't seem right.</p><p>for instance, a run-of-the-mill no-cycle Condorcet case (actually it was IRV and the Condorcet winner did not win) would be the Burlington 2009 election most of us are familiar with. in that case M=5. now if you
picked k=3 and chose candidate A to be Kurt Wright (who was the plurality winner and neither the IRV winner nor the CW), there is a set of (k-1) candidates (those would be Smith and Simpson) that Wright beat consistently. yet he is not the overall winner.</p><p>you can go to the Warren Smith
page or i can scarf up the numbers from the defeat matrix again.</p><p>how am i reading this wrong?</p><p>--</p><p>r b-j rbj@audioimagination.com</p><p> </p><p>"Imagination is more important than knowledge."</p><p><br /> </p>
