Those who dilute their approval across potential winning candidates are under-represented relative anyone with an extreme view who would apply a dis-proportionate approval level to their smaller (maybe singular) set of approved candidates. The approval or not of a given candidate might best depend on who supports them _at all_ out of the entire population, over any position in the rankings. That would mathematically simplify to ignoring rank order, considering all rank voting sets as approval tracks, and always eliminating whoever had the least votes until a single winner is left. However that poorly reflects the preference of selecting the most desired winner, which is why other slightly more complicated algorithms were designed.
