I'm not convinced.

Long time ago, several "good" riders told me that they kept the throttle flat open and went through the bottom with the foot on the back brake.

Me, I always came back one (on a TZ350) - my view was that I didn't give a good goddam who heard me do it. If they thought they could do better, then they could put their a**e on the seat and then tell me how to do it!!!!!
