I've learned a number of skills, and for me none of them worked in the way you're describing. I didn't learn to cut good miter joints by randomly vibe-sawing wood until I unlocked miter joints in the skill tree. I carefully studied the errors I made, and adjusted in ways I thought might correct them, some of which helped some of which did not. Then eventually I understood the relationship between my actions and the underlying principles in enough detail to consistently hit 45 degrees.
