Using the same ramp if you accelerate as if you have the "egg" under your pedal and your MPG meter states you are getting 12 MPG then by the end of the ramp you will have used 1.33 ounce of gas.

But what about the ending speeds? If you've dumped 4oz, but you're up to cruising speed, then you're done accelerating. If you've only dumped 1.33oz then you've used less gas so far, but have to continue to accelerate until reaching your intended speed.
It's got to be a trade-off. First and foremost, acceleration is situational, like slowmover said. In situations with more flexibility, I think there is a happy medium between hammering the throttle, and babying the throttle that creates the most efficient rate.
