I used to anguish over the same question with my Exakta VX, until one time in Peru an old Inca shaman clued me in on quipu. I modified the system a bit, tying a granny knot to indicate a bad exposure and a bow knot when I nailed it. I use a different color thread for each of my cameras. Works for me!
