What I am surprised at is how many Bow Hunters never practice except at the target range. I believe form work is very important - IN THE BEGINNING and then every once in a while. However, if bow hunting is your cup of tea then MOST of your practice should be out in the woods, mountains, forest and streams shooting the way you will hunt. if you are going to be a successful bow hunter you have to move PAST basic form. Look at an NBA player - yes I am sure most of them spent a volume of time in the beginning working on static form. However, as they progress they then move the majority of their practice to shooting under game type situations.
ALL that really matter is that the bow is drawn to the same length each shot (same energy imparted to arrow), the arrow is pointed to the spot you want to hit, and then you remain stable until arrow impacts. You do that consistently on every shot and I don't care how you stand, where you anchor, where your butt is, how fast you draw or shoot you will be a good shot.
Good form in NOTHING more then consistently releasing an arrow - the rest MAY makes it easier at times to do that..... but EVERYONE is different and a cookie cutter approach doesn't leads itself any better to archery/bow hunting then it does shooting baskets on the court.
We SOOOOO over complicate archery. I am amazed at all the tuning threads. Bare shaft, paper, broad head, filed points, FOC...... none of that will make you a better archer if you are not CONSISTENT. Crap just work on consistently hitting the same spot and you will know if your arrows are tuned. Same with form, if you are consistently hitting the spot at 25 yards then who cares if you have text book form. Having great BOOK form doesn't ensure you will hit squat if you aren't consistent.
Last point, this is traditional archery and I am sorry to let this cat out of the bag.... not everyone will be able to shoot like Jenkins, Welch or Hill...... we ALL have our limitations and we should LEARN THEM, ACCEPT THEM (and yes I know you can improve but accept them for what they are today - you could take Shaq and have him practice for three decades and he would never be a great 3 point shot - sorry that's life), and then work on hunting skills to narrow the gap..... not rely on new techniques, shooting aids, lighter arrows, faster bows, etc.....
