A fundamental standard is that the results of the voting method must be justifiable on the assumption that the votes are sincere. You can't do nothing except collect approval information and then elect someone who isn't the Approval winner because you make some "guess" about voters' rankings based on the assumption that there is a political spectrum. The least bad of these three methods, MAMAO, fails Irrelevant Ballots. Modifying one of your examples slightly, we see that the other two fail the Plurality criterion. 35% A 29% AB 05% BC 31% C As in your example they both elect B, but A has more first-place votes than B has votes in total.
