if its set properly, you shouldnt notice much if any movement! watch the pro's shooting BT you dont see movement...alot of the problem is your fighting the release! your body..arms,hands ect need to be relaxed so the back muscles work the way they are suppose to...tension is the enemy.
I used the squeeze me with great results. My advice would be to set the release very heavy to start to really learn to use the back muscles, this seemed to help me stop using my bicep and arm muscles to fire it. Shoot up close without worrying about the sight for awhile as well then start shooting the target up close and move back. I would warn against lightening up that release as it will be too easy to fake it and not use the proper back muscles. At first it should feel like its tough to get the release to go but once you learn the right muscles, your back muscles are much stronger so then it feels right. Good luck, its worth it in the end, I'm shooting better than I ever have now.
Thank you very much..Google John Dudley, and find articles by him. There are 2 Glade articles about back tension that are really helpful.
Basically you have to keep your bow arm shoulder down. If you let it ride up, it will seem like you are trying to pull a truck! That's because your bow arm shoulder blade blocks the movement of your draw arm shoulder blade, so you can't pull easily. There will be much more movement than if you are punching a trigger or rotating a release. You must develop the tension across your back so that you pull like you are making the arrow longer. That keeps the tension in line with the target. If you adjust the SQMe too light, it will go off when you press the safety. It's a balancing act, but it will teach you to use back tension if you will persevere and let it teach you. It's not a 3 day program!!
Dudley also has an article on shot sequence that is good.
If you haven't seen them, "Core Archery" and "Idiot Proof Archery" are helpful also.
If you will keep up this journey, you'll be shooting better than ever and more consistently.
