<div dir="ltr" data-setdir="false">Thank you for this response, Forest. I was reminded of this subject again when I re-encountered Jameson Quinn's work on Voter Satisfaction Efficiency the other day. According to his simulations, to be found here <span><a href="https://electionscience.github.io/vse-sim/VSE/" rel="nofollow" target="_blank" class="">https://electionscience.github.io/vse-sim/VSE/</a> ranked pairs performs quite a bit better than the Schulze method. This surprises me since I wouldn't expect much difference in practice (as I put in the original post of this discussion). I'm not sure if Jameson still reads the stuff on this mailing list, but it would be interesting to know what caused the difference.</span></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Toby<br><div><br></div><div><br></div><div><span style="color: rgb(38, 40, 42);">On Wednesday, 4 March 2020, 17:45:08 GMT, Forest Simmons <fsimmons@pcc.edu> wrote:</span><br></div></div></div><div id="ydp87d4fe80yahoo_quoted_1198119092" class="ydp87d4fe80yahoo_quoted"><div style="font-family:'Helvetica Neue', Helvetica, Arial, sans-serif;font-size:13px;color:#26282a;">
