Re Back tension

The only way I have found to understand back tension if you do not have a coach to help identify when you are doing it right is to borrow or buy the Formaster Training aid it's not cheap. Both the rigid set up used for reversals and the elastic set up will tell you when and how it feels to use the back. If you shoot an arrow using the elastic set up and you are not using your back the foremaster will exagerate the collapse of the shot.
