Personally, I think that the reason a lot of people feel they shoot better with a touch and go release is due to not maintaining back tension in a static position. What I mean is with a dynamic, non stop release some people keep the load on the back muscles. I think many people settle into a static anchor and stop pulling and just hold. Then, at release the force is no longer a push-pull motion but instead goes in the wrong direction (forwards, sideways, etc).
If you want to work on improving a more deliberate release try to focus on squeezing the shoulder blades as you pull through the shot. The drawing elbow at release should come backwards slightly as you drop the string. If it doesn't you're not utilizing the back muscles throughout the shot.
