So when you run a richer ratio for E85 you get more energy, hence more power, but you use more fuel. Methanol you use even more fuel but you cram even more energy, hence even more fuel.
Im not sure wether i agree totally with you or disagree with you because of the way you said it.

You in fact can run and should run a leaner mixture with e85 than you would gas. Lets not go get confused with how they have different stoich afrs, lets just look at lambida. Youll run a leaner lambida with e85 than you would gas.
