If you are shooting honest 3-4" groups at 40-50 yards, you are already close fortrue world class shooting. If you want to be a better archer, your improvement will come in the form of consistency, repetition, and the mental game that will allow you to do it under lots of pressure in a tournament with lots of people watching. The difference between what you are doing now and what people at the elite level do is that their bad shots aren't as bad as yours or mine, and they have the mental game to maintain focused under pressure.They still shoot less than perfect shots. You say you can shoot a 3-4" group at 40 to 50 yards, can you do that for 45-60 arrows without a single flyer? When you do shoot a flyer how far out is it? What happens for you on a 5 spot NFAA face, or 450 vegas face target? It is a huge commitment to make it to that next level. With proper coaching you can learn how to maximize the time you do have available though, that is the best thing I have learned. Lately with 70+ hours a week of work I haven't been able to shoot as much or practice as much. The practice that I do have time for though still allows me to continue to excel because I practice the right things. I guess my main thing is how bad do you want it, why do you want it, and if you really do want it, get a coach that can helpyou with consistency, repetition,and mental game. That is my advice.
