You might be interested in looking up the Feynman Technique. It's not by Feynman, actually, but by a blogger who based a learning method off of one of Feynmans observations. It's similar to what you do except it is used for diagnosing holes in one's knowledge and for learning complex material.

I've used it in my graduate program to teach myself some very difficult material. Still do now that I'm out, actually. The big difference for me is that I use a fountain pen and a notebook instead of a word processor. It's technically slower. Functionally it's faster, however, since I am less likely to get distracted.
