2 years ago I read a book by Bernie ________?...... anyway I tried to use his back tension methods and release techniques, and all else he preached.... WELL.... I was shooting in my back yard and realized I was flinching / target panicing and should have stopped because trying to shoot differant than I was used to wiped me out - I missed the target by 6 feet !! I had a brick wall as a backstop thankfully !! Needless to say I stopped reading the book !
