It has been said more than once, but no one has really focused on it. The key is good form. Bad form to parallel and bad form ATG will bring about injury. To be quite honest, most folks do not truly go ATG. If you video them you find they may go past parallel, but their hams and glutes are still so tight they can not get all the way down. I seek to go past parallel but like Carl said, "I don't train with a particular range of motion." I seek to train with good form and control.
When I was starting I would set my safety bars on the very bottom and then sit a broom stick on them. The broom stick was about 15" off the floor. When my butt hit the stick, I pushed back up. For us tall guys, 15" from the floor is a long way down.
