Well, I'm not really seeing people complain about the math itself, but instead more about fraud in the votes themselves, or machines/people cheating when tallying.
Just to be clear, the difference would be something like having to say B won because he was the most common second choice and beat every other candidates in a one on one. Versus saying B won because it had the most first choices, yet did not have a majority of first choices.
I think it's easy enough to understand that while someone had more first choices, they didn't have a majority first choices and since someone else had more second choices they took the win.
