I dont know of any tree system that starts when it turns green. You look at all the big cars that go out to practice at test n tune nights and they will sometimes wait 2-3 seconds or more before taking off and still run a 9 or 10 second pass. Again i have yet to see any tree system that starts the time when green. Even in drag racing competitions and events your et does not start until you break the beam. The win or loss is a combination of et and reaction time. You still get your same et but if your reaction time sucks you will lose.
My race against the 10 second 700awhp evo was a good example. I pulled a .012 reaction, to his 1.003 reaction. I ran an 11.54 to his 10.54. He only beat me by .03 secons or something like that. We basicly crossed the line at almost the same time. If he had been .04 later on his reaction i would have technically took the win in a drag racing event or bracket race. Even though he ran a full 1 second quicker than me.
