Question about the press rules for you Tom: are we allowed to let the bar dip down slightly with our arms to "simulate" a bounce before we start pressing upwards, so long as our legs don't unlock? I tend to do this on my first rep rather than Press 2.0, and am wondering if I should just 2.0 it (only reason I don't 2.0 is due to back issues, which wont be as much of an issue for a few reps in competition).
