I had a high school player who's father was a real Gravity Golf guy. The kid and his dad would do those drills for hours on end and they could seemingly hit the ball while hanging from a lamp-post. Both still had a tough time scoring, however.

The drills are goofy, and I have done a few of them in the privacy of my garage

That "small lean" you mention is good swing thought....
