.400 pro tree help

Pro tree..there is no last yellow..
Oh, haha. So it just goes from red to green, and you hit it? Like on Top Fuel? That would require a lot of total focus for sure. May help to have some kind of practice light at home, and a timer to record your reaction time. Prob takes a little work to hone that skill. How do the funny cars sometimes red light with the pro tree ? Just anticipating the green and jump too soon?
