A couple of points:

When the Condorcet Candidate gets the fewest top rank votes it is almost
surely because of the "center squeeze effect" which is easy to illustrate
in one dimension, and is easy to see in Yee Diagrams in the case of a two
dimensional issue space.

The voters who prefer the CW to the sincere IRV winner have a strong
incentive to rescue the CW from the center squeeze by insincerely ranking
her in top place. Of course the same gambit would work equally well with
Plurality ballots ... but wasn't adopting IRV supoosed to save us from
these Plurality manipulations?
