When you put the pedal to the floor, you're not trying for efficiency, you're trying for power.

Dropping to lower RPM for efficiency is what happens when you're done accelerating and ease up on the pedal. That's not what people complain about with CVTs. The complaints are about behavior and sound during acceleration, not after acceleration when you are merely cruising on low power output.

That might be you, but not me. I'm always trying for effiency. My cars never have the acceleration to make power interesting. I'm weird, but whatever.
