I also target .030 off the foot. If I am on my game, I can make small adjustments depending on who I am racing.

The thing I always tell kids about the transbrake/delay box is that if you miss the tree with the box, you might be .02 off and still have a chance to play the other end and win. If you miss the tree on the bottom bulb, it will usually mean a .090 light.

This is another reason the box makes an average/mediocre racer better.
