Assuming that Dook Goo Kau Bai is everything his reputation purports him to be as an invincible swordsman, what percentage do you think each of his "disciples" from future decades and centuries, such as Yeung Gor, Fung Ching Yeung, and Ling Wu Chung attained? If we set DGKB at his peak at 100%, what percentage did YG, FCY, and LWC attain during their lifetimes?
