You might be able to do something with my (three-candidate) fpA-fpC<br>
method, since it elects A in the situation where:<br>
<br>
P: A<br>
Q: B>C<br>
R: C<br>
<br>
since you have an ABCA cycle. In a 3-cycle, fpA-fpC lets each<br>
candidate's score be the number of first preferences for that candidate,<br>
minus the number of first preferences for whoever beats him pairwise.<br>
Highest score wins. Thus the scores become:<br>
<br>
A: fpA - fpC = P - R<br>
B: fpB - fpA = Q - P<br>
C: fpC - fpB = R - Q<br>
<br>
Since P > Q > R, P - R > 0, but Q-P and R-Q < 0, so A wins.<br>
<br>
Extending this method to four candidates so it meets Smith and still<br>
both resists strategy and passes mono-raise is hard, and is one of the<br>
things I'm working on (on and off) at the moment.<br>
