In DGSD, Wong Yu Yin was depicted as an expert of all things martial arts...at least in theory. She couldn't fight at all, but other characters had great faith in her ability to assess martial arts.
Based on what you saw in DGSD, however, how well-deserved was this reputation? Would you personally trust Wong Yu Yin's assessments, or was her miss-to-hit ratio not as high for you to be willing to trust the percentages?
