Mark--If you can do it without hitting the rev limiter, it should be worth a 0.1 at least, depending on how hard you are shifting it now. If you hit the rev limiter, then it will hurt because the car will stutter too bad. That's why I don't do it. But I don't let off much either, just enough to keep from hitting the limiter.
You might try it short shifting to get a feel for how close to the limiter you are going to get.
