Congrats :-)

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