Maybe but then say you are going to start later being we have an idea what the weather will be the next day. The last FAST race which should have started at 9am they said it would be 10am before hand but even that turned into after 11. Lost a lot of good DA in that time. Not every car is a 9 second car and most at that race were 12s and slower so was no reason to wait that long
Temps were around 50 when they started. I have made passes there in the 30s before
