Rod Jenkins told me something at his clinic that I found quite enlightening.

World class archers only shoot perfect shots, by that he meant this. If they set up for a shot and if at any point they shot isn't perfect they let down and don't shoot. He says they can do this as much as 20-25% of time. How often do we let down because it ain't 'right'?

We should let down and only shoot when it is 'right' that helps us ingraiin good habits rather than bad ones when we shoot less than perfect shots. I'm guessing for me it is probably only 50% at best that I have it all right and then half of those time my release could be better.
