Without a doubt Sensei! This is actually something I've felt lacks in specific parts of Japanese culture, especially in the athletic world. In football and in baseball Japanese teams will focus too much on repetition just for the sake of getting reps and without any sort of purpose or intention. In the case of football, Japan has often been labeled as having the weakness of not being able to score enough goals when it matters, even though they probably practice shooting more than any other country in the world. This clearly indicates that as you mention, there must be emphasis placed not just on quantity and getting in as many reps as you can but a progressive practice of developing quality, and consistently learning from each and every single rep you take.

Always appreciate your input!
