[EM] Approval ballots in "Four Condorcet-Hare hybrid methods"?

[Chris Benham]

I think it is quite a bit more egregious if the Condorcet faction can be 
successfully buried by a smaller faction, especially if the Condorcet 
faction is the largest.

So simulation information that casts light on how methods vary on that 
score would be interesting.
