Again, that's not what Pareto efficiency means; it means that the voting algorithm will rank A higher if everyone votes A higher than B. Going by your definition, no voting algorithm could ever be Pareto efficient, because everyone could just lie and say they preferred B to A when it's actually the reverse.
