Thanks for all the videos- I've watched Boris' a number of times - I don't THINK my butt is winking. I've got a mirror in front of me, but not to the side- I'll see if I can twirl it around outside of the cage with some lighter weight and see if I can catch myself. If anythin, I feel like my back is arching too much- with my butt going up, as opposed to going down- is this possible?
As far as depth goes, it would be more accurate that the tops of my quads are at parallel, so yes I've got ham to calf, but not for the complete length.
