LIL.
There's knowledge and there's experience. Sometimes you have both. Sometimes you have one or the other. The end effect doesn't really care whether the path to get there was knowledge or experience. That said, I'm an engineer by education. But I also spent 11 years on active duty in the Army dealing with what engineers often thought was a great idea. I was blessed. I had good NCOs and mentors who were willing to teach me the practical aspects of things, and I was determined to learn before I led. I work in aerospace in the defense industry. Going on 25 years now. I strive to apply my experience in the Army with my knowledge as an engineer. You probably won't be surprised to learn that a lot of engineers think they have great ideas until you tell them about the reality of how someone is actually going to use something they designed.
So, how does that apply to setting the chipbreaker? There's some physics that govern how a chip is formed and how tearout occurs. That's knowledge. But more importantly, it's an inexact science with a lot of variables. Experience is required to understand how sharp is sharp, how to set the chipbreaker, mouth, and blade projection to tame difficult wood. As Warren so aptly pointed out in so many words, you gotta learn by doing.
My two cents. And that's probably about all it's worth.
