In my experience, I think you are assuming wrongly. The efficiency comes from speed, and nothing else in my opinion. It could be because I am too dumb to grasp theory, and can not learn without doing and failing/succeeding and then subsequently learning from the outcomes (be it good or bad), but the most efficient way is to speed up the doing, speed up the getting to an outcome, speeding up the learning , and then speeding up the full cycle.
