I believe it's similar to IRV, except that every candidate with a
lower-than-average first-place vote count is eliminated, so one step
sometimes eliminates more than one candidate.  For example:


IRV picks C after eliminating B, but Craig's IFPP eliminates both B
and C in the first step (neither has the quota of 100/3=33.33 votes)
and elects A.  Note that B is the Condorcet winner!  I find IFPP to
be well short of ideal, although Craig claims that it's monotonic at
