By that measure Quantum mechanics as explanation is simple, because "it's according to Quantum mechanics" already covers everything. However that is not what I think of when I hear "complexity of an explanation", I do not think of the complexity of the statement referring to the explanation, but of the complexity of the explanation itself, which is only referred to by the statement. Also I disagree with using the number of experiments needed to arrive at the conclusion as a measure for complexity. By that measure "things fall down" is complicated, when you have done a lot of experiments. I would rather take the number of "steps" needed to derive it from first principles once you know it. But also that sounds like what you said in your last sentence, so you are contradicting yourself?
