What's the perfect R/T?
Well, if you are running on what's called a "sportsman" tree, that's usually a .500 light. If you are running on a "pro" tree, that's usually a .400 light. And some tracks, like my POS local track, print reaction times out with a .000 being perfect. So a .510 sportsman light would be .010 at my track. BTW, on a sportsmans tree, it's a .500 light because that's the time between the last yellow going out and the green coming on. And on a pro tree, it's a .400 light for the time between all the yellows go out, and the green comes on. That's why it's hard to cut a good pro tree light, you have to be quicker
