I had read about that method of using a BB gun & tried it a bit on my own, no official training. Was using the Daisy Pump (no rib Stan), model 29 if memory is correct. I didn't do it enough to get as good as some of you, but it will amaze you just what can be done by this method of "Look at Target" & shoot. Obviously the Daisy didn't fit me like my regular shotguns but still shot well to point of "Look".
