RE: FOC calculation
I don't have a scale, any idea what an average weight would be for a nock and fletching? Thanks.

RE: FOC calculation
AMO-Standard F.O.C. balance formula
F.O.C.%= 100x(A-(A-L/2))
------------------
L
Example FOC Calculation
Balance Point Length 17.25”
Arrow Length 28”
Arrow Length / 2 14”
(17.25-(28/2))*100/28 = 11.6%
17.25-14 =3.25
3.25*100= 325
325/28=11.607%
