The AVERAGE vacuum level in the engine won't change, and the pumping losses from the throttle are related to the AVERAGE vacuum.
I believe this to be incorrect. A pressure wave that arrives too early during the intake stroke, will increase the mean pressure without increasing the final pressure in the cylinder. And that will decrease the pumping loss without increasing engine load.
