Hi,

This is still Yee diagrams, right?

Kristopher is just saying you *could* attribute it to voter ignorance,
and if you don't, if everything is sincere, you're not going to see any
equality of ranking because preference is based on distance.

If you try to incorporate strategy into a Yee diagram you will get most
methods looking pretty odd, I expect. For instance I usually implement
"strategic FPP" and "sincere IRV" in exactly the same way, at least in
the three-candidate case. So oddities usually blamed on IRV would show 
up with FPP as well.

It's also pretty well-known that if you include pre-election polling as
part of an Approval implementation, it isn't monotonic (at least in any
setup I've seen or thought of).
