The thing about that form and taking it to the fundamental letter by following every detail, is that your entire shot comes together. Where I have seen many go wrong with it is when they try to work on every aspect of that form at once. If you work on each part individually, from the grip all the way to the follow through, the learning process is quicker. The other one is the release, Schulz teaches a very strong release, even though he keeps it in his face. The release I see fellows quite often do is, they release soft and then after the arrow is long gone they pull their hand past their ear with what they call a follow through. When you get to that hard short Schulz style release, you will see tighter groups, better arrow flight and increased arrow speed.
