Here's another way to explain the same numbers.

Initial opinions:
6       B>A>C (or B>C>A)
2       A>B>C (or A>C>B)
5       C>B>A
4       A>C>B

B would win. But before the election the two A>B>C voters will change their (sincere) opinion to (sincere) B>A>C. As a result C will win. B thus got more first place support but lost the election.

1. Dopp wanted simple nonmonotone IRV elections examples.
See

and here is another:

#voters  Their Vote
8        B>A>C
5        C>B>A
4        A>C>B
If two of the B>A>C voters change their vote to A>B>C, that causes
their true-favorite B to win under IRV.
(If they vote honestly ranking B top as is, then their most-hated
candidate, C, wins.)


2. Roullin advocated "median voting".  That is discussed here:

http://rangevoting.org/MedianVrange.html

median has a lot of disadvantages versus averaging, but few
advantages - which in my view are
not enough.

3. Bolson's page on IRV
http://bolson.org/voting/irv/
I agree with it, he has independently reached the same views
as mine
