Congrats :-)<br>

As for Condorcet winners: if politics is 1D and there's not too much <br>
noise, there will be a sincere CW. If opinion space grows, say by more <br>
parties being established, then you could get sincere cycles, but not <br>
necessarily. So the lack of cycles shouldn't be too surprising... I <br>
guess if anything, it's most surprising in Australia, because the Senate <br>
has multiple parties. But from its House of Reps composition, it might <br>
just be that IRV's compromise incentive is too strong.<br>
