People have tried all kinds of combinations over the years and have found that the most consistent is to go on the stop immediately after launch. You get a nice hard launch to get going, then immediately (say w/in a 0.1 seconds) you get on the stop. You're still accelerating, but at a rock solid consistent RPM, very repeatable.

If you go on the stop later, especially in low gear, the engine has so much power that it will "climb" (RPM going up) on the stop, pushing past your "dead stall" (desired RPM on the stop), and become wildly inconsistent. That's also why the bigger the HP the sooner you shift. We shift at 1.0 seconds because any later and the engine wants to climb on the stop.

The Super classes are all about consistency and repeatability. After lots of people have tried lots of things, it's been found that this works best.
