This statement makes me wonder if I'm doing leg presses correctly, because I can rep 720 pretty easily (after doing squats) and I'm nowhere near the strength or size that you are.
I'm 90% sure I'm going down as far as I can (I even try to lift my heels up slightly at the bottom of the rep to get down a little further), but I'm using a ridculous amount of weight it seems with leg press, and I'm only squatting 285lbs for reps (I'm all natural, only been working out for a year and a half so cut me a little slack, haha)
