Lol, Thats really bad for your transmission. Once you get it down you can shift fast enough without breaking anything, And the difference between a good fast shift using the clutch and powershifting is negligible. Double clutching is for tractor trailiers. Thats when you put your car in nuetral, let the clutch out, wait for the engine to match rpms for the next gear, and push the clutch back in and put it in the next gear. Thats why they put synchronizers in transmissions, they do all that for you. I remember that line in the fast and the furious "granny shifting and not double clutching like your supposed to. who does that? haha. Its just a waste of time, But im sure it would make your synchros last a little longer.
