Ok, maybe its been done before, but I sure like it. Im kinda anal about checking the brace height on my bow. I took a couple of practice arrows and measured them from the nock to about 8" down the shaft and made a "scale" so to speak. When Im shooting, I've noticed that there is a little stretch each time I string up the bow, then it settles in. Seems like those first few shots may be throw-aways. Anyway, if its something you constantly check, its an easy trick.

Andif Im just figuring out what everyone else already knows, sorry...
