What you are experiencing is part of a fairly normal progression in learning any hand/eye coordination sport.
When you learn something new, you first have to learn it cognitively (with words and directions). Words and directions can only take you so far, because there is no way words and directions can control all the hundreds (thousands?) of micro-movements needed to successfully accomplish a complicated hand/eye coordination movement.
So at some point, when the words and directions have taken you as far as they can go, you switch over to experiential learning. You have memorized the gross movements by using words and directions, and you don't need that anymore. In fact, words and directions will prevent you from learning with your body, which is the experiential phase. So you shoot and shoot and shoot, maybe hundreds or thousands of arrows, re-learning what it feels like to use the new method without having to think about it in words anymore.
Then at some point, something good happens. You're shooting hundreds of arrows using your new method and hopefully enjoying the experience. You try something a little different, maybe subtle and hard to describe in words, maybe without really meaning to try anything different, and it works better than what you were doing before. You had an inspiration. That's why they call this phase inspirational learning. From this point, your learning proceeds like stair steps: flat periods where you don't improve, or maybe even get a little worse, followed by inspirational jumps.
Maybe at some point you hear of a completely new method you want to try, and start over again at the cognitive level, and then repeat the whole process all over again. Cognitive, experiential, and inspirational; that's how we learn hand/eye coordination sports.
