.000 is a perfect light. At my strip, footbrake classes with no box, no cross talk, you need to have a zero after the decimal to be competitive. Classes with those electronics, you need two zeros after the decimal to be competitive.
I only TnT, so I don't really care what I cut for a light, i'm always looking for a "best" E.T. :D Sometimes on Saturdays, they don't have enough TnT cars, so they make us run with Trophy. Then I get 2 "time trial" runs, then competition starts. So in my head, I have at least 3 time trials..... lol..
