If you currently have 1.100 or less delay leaving on the top bulb with a full tree, you won't have any delay on a .4 pro tree.
If you run a class that uses a .5 pro tree, you can use the box if you have more than 1.000 delay.
As an example: let's say if you have 1.060 on a full tree, you'll use .060 on a .5 pro tree......
If you use 1.130 on a full tree, you'll use .030 on a .4 pro tree and .130 on a .5 pro tree.....in theory.

I guess I was thinking that if you are the slower car on a .4 pro tree that a box would be usless

If you have a car that reacts quickly, then you could still use a delay box on a .4 pro-tree. But, there is no "slower" car when a pro-tree is used. Other than the Pro catagories and Alcohol catagories all other cars that use a pro-tree run on a preset index...such as Super comp, Super Gas and Super Street in NHRA and Super Rod, Quick Rod, and Hot Rod in IHRA. Of coarse Super Street and Hot Rod run on a .5 Pro tree.

I have been to a track where they use the .4 pro tree for bracket racing, therefor I dont see where a slower car would benefit with a delay box, where the faster car can use cross talk or cross over and come off the slow car light
