Would it be considered a mutation to have more mitochondria than average? I hadn't considered that.

I also like the idea about midichlorians simply being a side effect of being Force sensitvie.

I think Lucas tried to leave it fairly vague. I mean he presents what the Jedi and more specifically what Qui-Gon believes, but there are a lot of theories that can be drawn from the co-relation between Midichlorian count and force sensitivity.

Was the Jedi Order even right about their theories?
