From a clip I seen (approx 1/2 an hour) Dick would say he "Walks the car out, then Hammer it." A crew set up a in car camera. His clutch foot went to the floor and back up in a 1/2 blink of the eye. Lighting quick. Is even bet his foot came up quicker than the clutch pedal on its own.
I myself would just slam the pedal to th floor and let it slam up on its own. Just slide the foot to the left off the pedal. BAM! Engaged!
