If you can't redlight on a pro tree, you might consider deep staging ( if allowed). This will hurt the ET slip by as much as a tenth , but in a bracket race , it's all about the reaction time. Why it hurts the ET and helps the reaction time is simple. less roll out so the staging beam is broken sooner/ Your car is till running the same , it just has less of a running start so to speak. Drive by wire cars are THE hardest to cut lights with. Your foot hits the floor and the computer is still playing catch up. Hard leaving (1.40 or lower 60' times) sometimes need "delay boxes" so drivers don't redlight. It's also harder to redlight with a car that has allot of front end travel as it's going up instead of out.
Just a few observations from 50 years of doing it.
