It's kind of funny that something that has become second nature to me can be a chore to describe in detail when you slow it down and have to consciously explain in detail what you're doing and why. Remember the National DE Instructor school? Unconscious/ Competent.
In the interest of growing more and better drivers, I'd like to augment that written lesson in the mag with a video I made some years back. I was practicing camera mounting angles for shooting future videos and was messing around calling the gears in my best broken German.

Since 944's have an accellerator that hinges at the bottom, it's more difficult to use your right heel to blip the throttle. It looks as if I'm using my heel to hit the throttle in the video because my right foot covers the gas pedal. In actuality, I'm blipping the throttle with the outside edge of my right foot. The inside edge is still on the brake pedal.
