With an auto without a 2-step or transbrake I wouldn't even bother brake boosting at the line. As as already been said, you aren't looking for the best ET's, just consistent ones. If you get really serious, then you will start to build up a log book, which shows what ET you ran at what track, and under what conditions. Eventually, if the car mods stay consistent, you will have a very good idea of what your car will run at a given track and conditions. Try to keep your car warmed up to the same temps each time you are ready to make another run. This helps you stay consistent as well.
My philosophy has always been to run your race and don't be concerned with what your opponent is doing. You may think that you are breaking out on a given run because you are really far ahead in a run, what you don't know is what kind of reaction time your opponent had. Also, try not to get worked up when waiting for your side of the tree to cycle when running against a slower opponent, you'll get jumpy if you aren't careful and could red light.
I have been in my share of bracket races before and they can be quite fun. The last time I was in one was when I still had my Mustang, and it seemed like my side of the bracket was full of 14 and 15 second cars. Running 4 and 5 seconds faster and having to to go feels like an eternity and it was really had to judge how I was doing come the finish line since I was out trapping the other cars by sometimes 40mph on the big end. It was fun and I finished third. I want to get out there with the truck if I ever get some extra time on a Saturday.
