Ok, many of us assume that a LOCK Great has seven times the power of a QZ master because it takes seven QZ masters, with a formation, to match a Great in combat. However, that is not considering the inefficiency of seven people fighting one. There's no way all seven of them can direct their full power toward their target at the same time, and no way a single Great can counter seven pairs of arms or seven swords coming at him at the same time. That was why the formation was created, to achieve better efficiency. The QZ masters can direct more of their power toward a single target, but it still does not mean 100% efficiency. So, in conclusion, I am making the bold statement that one Great = less than 7 QZ masters in raw power (3 or 4 suits me better)
