This is a common misconception. A delay box would be *more* useful without reaction times shown on a timeslip. Go to a test and tune, roll numbers in until you turn it green. The only time you'd have to make any serious adjustment would be going from track to track to make up for rollout differences, but with just a small amount of data, that hump would quickly be overcome as well -- and the delay box user would be able to make those compensations much more quickly and accurately.

It is a little hard to understand how anybody could drive a car that goes 1.10 60ft. times and not go red on the bottom bulb or get out of a that car and jump into a car that goes 1.40 60ft and everything is dandy . Bottom bulb my a** . Have a nice day

Slow transbrakes, long buttons, different tire sizes, different converters, different chassis setups, blinders, etc. It's not exactly a black art.
I made one pass in a SS/CM car a few years back. I assumed that the rollout would be very quick, so I 'hung' the bottom bulb on just a hair, and came up .032 or so. I quickly figured out that the rollout was actually identical to the Stocker I was driving at the time.
On the flip side, I've also driven cars that had the same 60', ET, and MPH, but the rollout was as much as a tenth different between them!
Having incrementals on a timeslip allows you to spot problems in the car, or heaven forbid, in the timing system.
