Yeah, I've done this a few times, and it really helps with my understanding of the code. Often I have found that colleagues or managers view the time as wasted, and I get comments such as "Why did you waste time rewriting that code?", and my replies of "So I could understand it and make the code clearer at the same time" falls on deaf ears. But definitely a good technique, thanks for tip :)
