I think sometimes it comes down to something as simple as what class you run after. I have a very close Friends that I tried for months getting him to hold back jumping up in line. As soon as they called a class his starter was engaged. FINALLY last year he waited till several cars were lined up in front of him. Never many but a few groups. his 60 foot times closed the gaps and he started going rounds. well guess what???? He went back to his old ways this year and is frustrated to the point he's said he needs a BREAK from racing. Street tires, radials, and slicks don't always take the same track prep so I always drag my feet when heading to the lanes as I run slicks and want their rubber laid down and the water gone that "street tires" drag to the starting line.
