Thats great advice Martin Cougar... I keep a index card in my bow box with all measurements such as :

Nock height
nock to kisser distance
nock to peep distance
arrow rest launcher arm (muzzy ZE)
turnbuckle length
set screw for rest height


This really helps if you need to change a string during the season. You can at least get close to your original set up and save a little tuning time.
