theres very little purpose behind it, but it does contribute to getting where youre going quicker.

For one, its just one less thing to worry about when focusing on shifting as fast as you possibly can.

As for actually making the car accelerate faster... sort of, it can. Since you will hold the engine at redline for the momentary duration of the shift, once you left up the clutch pedal, you get a mini "neutral-drop" effect, similar to the surge in wheel power an average automatic transmission gets when it upshifts. The inertial energy in the flywheel and crankshaft gets sent to the tires as the drivetrain has to suddenly slow the engine speed down to stop slipping.

edit: This is the same exact energy that causes the wheel chirp when you shift very fast normally, it just amplifies it with a little more RPM.
