Write down for each bow nock point height, brace etc. I'd keep a list somewhere in the "bow room" so you will have it. I think I'm even going to add string info just in case. That way if it moves you just look at your list and see where to put it back.
That's what I do anyway, but I haven't had one move on me yet. I use the little brass ones till it's tuned in then tie on....
