Did not know there was another way.

Or just hold the brake, put in gear, then release the brake, rev up the engine to 3k rpm and release the clutch. Not as good for the motor and gearbox but faster lol

Edit: Ya'll, if one knows what they do, and knows the car, speeding the motor up to a specific amount, often 2-2.5k rpm, and releasing the clutch a specific amount, takes less time than gravity needs to overcome the inertia. I'm almost always literally starting while practically still standing, because it takes ~0.1 second to do said things, if you know the car and its sweet spots.

Rev match downshifts.

There are a few possibilities:

• It's faster, especially if the handbrake isn't applied already.
• Some cars, like the one I drove most of the time in driving school, have an automation to keep braking for a second, so one just needs to: Brake, Clutch, Put in gear, Release Brake, Rev up engine a bit, Release Clutch.
• My current car's Handbrake is basically non-functional, so I have to do the fast foot shuffle.
