As I was organizing recent brew notes I remembered my favorite quote from Myth Busters. Adam Savage once said "Remember kids, the only difference between screwing around and science is writing it down". Apparently one of their technical advisers said that phrase and Adam said was going to use that one day on the show. Loved that show. They did a lot of screwing around and in similar way so do many home brewers. So be sure to write it down and you won't be screwing around!
