Skid pan and standing start lap dash is closer to drag racing in terms of clutch (ab)use.

The problem with Tino's clutch at the moment is due mainly to insufficient room between the flywheel and the front of the gearbox. The Tilton uses a hydraulic throwout bearing to push the clutch instead of the usual fork/pull arrangement. When Tino went to the bigger 225mm clutch Jim had to shave as much space as he could to get it all in there.
The bearing has 6mm of stroke, the clutch needs 4 mm to release. There's a fine balance to get it working right. Unfortunately there's no adjustment, only by machining spacers under the bearing, which obviously require the box out.
As the clutch wears the fingers lift, thus closing the gap more. So the trick is to have enough of a gap that there's some room for some wear, yet still have enough stroke to fully release the clutch.
