When he was just fifteen years old, Mo Yung Bok was able to easily defeat the Yellow-Browed Monk and similarly skilled wulin adepts. During the next five decades, Mo Yung Bok continued to train his martial arts...acquiring the skills of many different sects and individual martial artists. Despite this, however, by the time he was in his sixties, Mo Yung Bok was "merely" at the level of Kiu Fung. One would expect that with the talent that Mo Yung Bok exhibited at the age of fifteen, by the time he was in his sixties, his training should have placed him in the class of the Siu Yiu Sect Elders (if, indeed, not the Janitor Monk). Five decades of training after his spectacular demonstration of prowess at age fifteen, however, Mo Yung Bok was "only" at Kiu Fung's level. Was Mo Yung Bok an underachiever?
