Well, i'm just there for the "best" ET I can get. My work schedule most of the time won't allow me to attend Friday night Test-n-Tune. So if I go, it's usually Saturday. Most of the time they have TNT on Saturday, but if not enough participants in TNT, they make us race in Trophy. Then I get two time runs, then elimination. I use elimination for TNT also, hoping I break out LOL :D. I just know if I run on a hot and humid day, that's the slowest my car will perform. I know enough racers down there, I can usually tell how much their car is effected to know about what my loss is.
