okay.. i think I solved the problem..
the track i'm running at (bristol dragway) has "street fight" nights where you can just about bring anything and run.. no brackets.. no money, no nothin..just come., pay 10$ and run for the hell of it, or race your buddy etc.
I talked to a dude that does actual bracket racing and the like and he's also taken a street car to this deal and the way he explained it... a perfect light would be .000.
they aren't using the .500, or .400 whatever timing cuz it's just a buncha yahoos (me) out there running and we would never understand that stuff anyway.
