I know they have cronographs,but is there a method to figure out how much speed you lose when you take a inch off your draw length? or when you add weight to your arrow ?

Hhhmm.... I imagine there are brainy types that know a formula for those changes... but I'm not one of them. ;D Hopefully someone will chime in soon, if not, I'll ask my buddy at the bow shop when I go in to work on one of my bows Wednesday and see what he can tell us.  |

i got this from another web site , they say you lose 10 fps for every inch of draw length you go down and 1 fps for every 3 grains you add on.
