    How accurate is this?

    This year is my first year of archery (wife bought me a bow as an anniversary present).

    After initial setup and tuning in original set of arrows, I decided to see what else was out there, and to conduct some research on what best would work.

    I attached to this post an arrow calculator that takes arrow specifications (length, gpi, fletching nock, tip weight), and bow specifications (IBO speed, draw length & poundage speed reductions, weight on string), to calculate the estimated IBO speed of an arrow shot out of a bow, as well as kinetic energy.

    Can anybody comment if this is an accurate measure of arrow speed & kinetic energy? I have not been able to chrono my bow to compare this. Thanks guys for the help.

    This page should get you close to what your wanting to know. I shot my bow through a chronograph then calculated it with the web page and it was within 5 feet per sec.
