That only really matters if you're racing against someone or trying to get the best ET. Timer doesn't start ticking until you move. You can sit on the green for 5 hours and your ET won't be effected. Launching on the last yellow only improves your R/T.
That's why I told him earlier in the thread not to worry about it his first time out. When he starts bracket racing, cutting that .00x reaction will be key
