Yes it will happen and has happened to me. The problem is, if you focus on it so much, it takes a lot of joy out of shooting. My son has DQed for several different reasons and not the same one twice. The problem now is he is terrified of doing something wrong and shooting is not as much fun for him.
I think it’s the old adage, don’t focus on what not to do, but focus on what you should be doing right. It’s working with him, just have some scars to heal from. And yes they are important scars, he definitely learned from them, we just don’t focus on them.
