Working on all areas of surfing, by focusing on them one at a time, is a proven way to develop the whole performance.
I believe he is, looking at the evidence. With 11x world championships to this date, with him almost snatching his twelfth in the Pipeline Pro in late 2013.
I believe so, by the amount of time and effort surfers put into their training. In many cases, far too much time in my view.
You see, many champion surfers before they made their mark in the sport, were good at other sports.
