School me here! l don't understand how it helps in bracket racing. Seems like all it does is make the rollout a lot longer and thus the car run a diff (faster) number (i.e. a rolling start) but who cares? It would always do this so it seems like the dial-in takes care of that?

Now in class or index racing, I can see where it would make for a faster ET so the motor doesn't have to make as much power to run the number. Maybe helps if you're struggling to run a number.
