I understand that all our wants differ, For instance I only want to have a decent grasp over software engineering to sustain a livelihood, but even if I wanted to master all of computer science, I don’t know if I would equate using a timer(pomodoro) or recalling the answer without looking at the answer(active recall) to mastering compiler design. I don’t about you, but to recall the answer without looking at the answer while preparing for a test or studying for a stipulated time before losing focus didn’t need a overly sophisticated term at least up until a couple years ago. Most of us did pretty well through our schools and colleges. What is this all of a sudden now, if not money grabbing, avarice, charlatanry, fraudulence? In fact, I would’ve conceded if the benefits of these sophistication were extraordinary, they are not even marginal. Anyway man, be well:)
