After Fringe, what notes do you keep before the whole month becomes one blur?

I’m thinking less about reviews and more about useful evidence for the next version of a show. By the end of a run you can have loads of tiny changes, bits that only worked in certain places, and ideas you swore you’d remember. What do you actually write down after a run — cuts, strongest sections, where attention dipped, new lines, running order changes? And what do you deliberately leave alone for a week before deciding anything?
