I have referred to one friend before, but. If you would watch him shoot now, you would say that he does not have TP. Can he hold a bow back for 4 seconds and still have a good release? NO. He bought a recurve, then he went to an archery shop to buy arrows. They gave him a pvc pipe with a bow string and a captive yard stick, to measure his draw. The guy told him 'you are not stretched out yet pull, pull further.' He ended up with full length 2317s with 125 grain points for a 54 pound recurve. He was told that he should have a 31 inch draw, he is 5' 10" tall. His efforts to make those arrows fly, frustrated the hell out of him. He came to me for help, I use to shoot lots of target bows, but I only teach one shooting style for hunters, John Schulz. It is my choice and I am sticking to it. He learned it very quickly, but then later, he got online and read about long holds and all kinds of other things. It all got his wires crossed and he could not come to anchor.. One day he tried something just the same but way different. He took those 2317s, they never did work and they for sure were not going to work out of his new, my old, longbow. He went out to his concrete silo and proceeded to blast them as hard as he could into his silo. The effect of destroying those arrows until they were unshootable allowed him to get to anchor. He still could not hold for four seconds and hit my deer target, but he didn't care. He outshot me, shooting with the same one second tempo as John Schulz. He said that when he visualizes shooting a deer, that is the shot that he has in his head and that is the shot that he is going to take. Trying to do anything else messes up that visualization. Part of the form is being on target when approaching and reaching anchor, it needs to be practiced separately when things are off. For some, forcing a hold after anchor is simply not in the programming. If someone is consistently shooting good out to 30, maybe there is nothing to fix, then possibly a maintenance routine of keeping the individual pieces and parts of the total form in working order is all that is required. He has become a very successful bowhunter.
