Slower ok, I'll slow it down even more and try it again today.I think that you are practicing too fast to learn a new motion. Try half that speed. The main goal is to get the intended motions working and repeat them until they work “automatically.”
Your German grip looks more like an American grip to me which is also OK. Use what works.
Thanks everyone for your comments (even those unhappy about this), I learned a good deal of things by experimenting and digging more.
