ibo vs actual speed
Can any direct me to the link for this. I did a search here a few weeks ago found it no problem. Now I can not find it.
What I am looking for is the set of factors that I need to take into account for figuring out the estimated speed of my arrow based on my set upie subtract7 ft per sec for every inch my draw is under 30, subtract 4 fps for everything on the string.stuff like that.
Thank
Mike
