For a coach, this advanced detector really is a great secret weapon! Dai Li exclaimed to himself.
Dai Li had been with the national team for some time, so he had realized that the training of first class athletes focused more on well-targeted small detail improvements. The physical qualities of the athletes who were on the national team were definitely impeccable. As a result, there were never any major shortcomings in their techniques. Therefore, besides the difference in ability, details were the dominant factor in the gaps between the athletes.
However, it was extremely difficult to pinpoint these small, specific problems. The techniques of the athletes had been developed over a long period of time. They had stuck with the same training methods for years—some even for over a decade—so it was very difficult for athletes to find these small problems themselves. Usually, only top athletes were able to recognize the small problems in their training.
