"every time you tapp the cc lever, you excite the system, which produces much sharper impulses than you do with your foot. those sharp reactions inevitably cost mpg's."

That is an ASSumption! It may or, most likely, may not be true! The fact is the pedal position is converted to a digital value BEFORE the car's computers can act on it. It well may be that the minimum change in pedal position as seen by the computers is greater than the correction given by the CC. I suspect that the changes that CC induces into the powertrain following a tap up or tap down are in fact smoother than can be achieved with the foot, this suspicion is supported by watching the ICE power output, with Torque, under both driving techniques.

"how much are we talking about? aye, there's the rub."

I basically agree. It would be a very tedious test procedure to substantiate either method as superior and I'm very sure the difference would be VERY small. So I prefer to rest my legs and use my fingers.
