You're basically describing a "pulse and bleed" strategy, and I don't think it works. (At least I've never been able to come out ahead the few times I've tried it.)

I think a strong "pulse" (accelerating briskly, near peak BSFC, up to speed) will only pay off if you maintain a high mpg for a long time afterwards, or if you plan to immediately follow it by a glide, and rinse/repeat.
