We haven't seen any gains by doing the pedal dance over regular disengagement of the TC on these cars on track. Some folks say that it makes a difference but from our tracking and racing with the tires and suspension setups we use there hasn't been any differences. Turning off the TC eliminates all but the most intrusive elements and on the road course if you are getting into that you are likely not driving the car smoothly. Pedal dance is required for the halftime show stuff like drifting
