GMMAT,what you are doing is fine but if you plan on shooting nationally in the bowhunter class,you MIGHT want to step back LOCALLY.I really think all Ausie is trying to say is don't get a false sense of security.
The national level bowhunter will not be anything like your local level bowhunter class,atleast not in my experience.The max might be the same but the average will go way up.So will the competetion.If you plan on competing at THAT level(,which I assume you want to just from reading your post,youseem to be verycompetetive)stepping back a class would be good practice.
You ARE doing GREAT,especially for a first year shooter and you are doing it the right way.You have concentrated on learning form and technique which is crucial and the results are proving it.
BUT,whatever you choose as your course of action,have fun traveling down the path.
