Title: FOC % Question
Post by: Recurve50 LBS on April 21, 2009, 01:37:00 AM
Ok guys,

I found the length of my arrow measuring from the base of the nock groove to the very front tip of the point. Measurement was 30 1/2" . The center of the arrow is 15 1/4" Then I found the pivot point and measured from the center point. That measured 5" . Now how do I do the math to figure out the FOC % ? I never was very good with math when I was in school.

Thanks Gang

Try this,

5/30,5 = .1639 ( 16.4%)
