Two things I have learned:
Just because you have a "title" doesn't mean you know your butt from a hole in the ground. ( Teacher, Coach, President, Parent)
Just because you can win a "event" doesn't mean you have good mechanics it just means you can win maybe you just have more talent talent than anyone else on the planet.
Good advise is good advise and in archery any time you advise someone to have bone to bone contact over the corner of the mouth or earlobe you are in the good advise side of doing things. Any time you advise someone to have a surprise release over a punch style release you are in the right. I could go on with examples but even though i have 21 years of coaching experience in basketball, baseball, and football I have never had the title of archery coach given to me nor have I earned money doing it.
