I always run the car flat out and see how fast it is running that day. Then I dail right at my fastest et and try to cut a good lite and win. My car is usually pretty consisdent and I figure it will run within a few hundreths of my best et. So if I cut a bad lite I will loose anyway. But if I have them covered in eliminations I will hit the brake and slow it down. Good luck as I want to go but dont know if I can make it. Ron
