What mods did you run with?

Yeah, it's amazing what a difference even an hour can make. When I ran my 13.85, an hour later I ran a 13.96 and actually had a quicker 60' time by a few thousandths. I check the DA on each and every slip because it fluctuates dramatically once the sun goes down and the humidity picks up.

What first clued me into the DA's was when I was bracket racing with some friends of mine. One of my buddies had a hand held weather station to check the DA with and although I thought it was overkill at the time, I have since changed my mind, lol. Those guys talk about running a particular time with a 7 or a 9 and what they mean is the time they run, say a 10.55 with a 6. The digit they are talking about is how many thousandths and to win the brackets at my track, you better have a .030 reaction time or better and be able to calculate how your vehicle will run to within .009 of actual time or you will be putting it on the trailer early.

I have so much more respect for the bracket racers than I used to because having tried to run with them and tell what my truck will run in changing conditions made me realize that you have to be part scientist to win at it.
