This is turning out to be an interesting thread.

There are two functions with double clutching.

One is the match the gear speeds to alow engagement.

I guess on a proper syncromesh transmission it is not a required function except it dose reduce the wear on the sycncros and engagement teeth.

The second function is to match the flywheel speed to the drive train / rear wheel speed so traction is not upset when the clutch is let out and the rear wheels have to compensate by quickly slowing briefly.

The second function is vital to proper car control to keep the rear from loosing traction under braking into a corner such that is might upset the car.

Thus, if one has a good syncro system it could be that one might be as fast or even faster if one dose not 'double' clutch' and only 'blip' just after the shift.
