I know I'm not typical but if I come up with something that I know I'm going to use on a track I'll definitely leave it patched up for months at a time. Yes, I'm a slow worker haha. If end up needing to use some of the modules involved then maybe I'll write the patch down before disassembling it. But I have a pretty large system so that's not always necessary. Anyway I think this kind of thing is highly individual and just depends on your goals, your method of working, the size of your system, etc.
