What is the difference between "practical" and "experience" in terms of learning a skill or expertise?

I don’t think there’s general agreement on what this distinction means.

For me, “practical” means that you have organized your knowledge for solving problems. You know both “know how” and “know why.”

Experience means that you’ve solved that class of problem many times, so you know what’s hard and what’s easy, how things work when they work, and how things work when they don’t work. You’ve seen it all. That makes you much more efficient than you were when you first started solving that class of problem.
