I've done a bit of thinking about sports and other skill based activities and realized that the thing separating pros and amateurs are fundamentals. Take tennis, for example. The top seeded players all have fundamentally sound strokes. When you begin learning from a teacher, they teach you how to hit correctly. In higher levels of high school tennis, the good players have better strokes than the worse player. This also applies to a game like Go . The pros say that fundamentals are what make them different from amateurs. Basically, fundamentals are the most important. So, I was thinking that this should apply to cubing also. If so, this might change how one gets better at cubing. Does cubing have fundamentals that set WR holders above sub 30s? If so, what are the fundamentals?
