everyone has their methods and forms, but when you start getting a certain size, range of motion and a lot of the form goes to shit, look at cutler and most of these guys lift in the gym... they do a lot of weight in small concetrated spurts. It's obviously working for them and him, so do what works for you. No disrespect I think was intended by anyone and that's fine, but calling them quater squats ... please. have someone film your workout and post a video of it.... because going back and watching it you will most likely be embarased by your own form, weight and size.
