Several times, alternating with and without to eliminate any trends and the tester can't know whether it's with or without. The answer is already known, it won't make any difference apart from the tiny fraction of a second it takes to push the pedal further. It's just about whether you like the pedal response or not. If you like it then it's good.
Joe I assume by your comments that you have never tried a sprint booster. I can assure you that you won't need to tell the tester if the sprint booster is on or not as it is in your face obvious by the difference in performance. After you have driven with one on, turning it off is like you have gone into limp mode.
It is a bit like saying rather than buying a faster computer I will tap the keyboard faster to make up the difference
