FOC method that I use for my20” BEEs (Note - FOC = Front of Center)

1. Total arrow length minus the BH/FP on myBEEs = 20.5” (nock to insert)

2. Balance point with BH/FP installed on myBEEs = 14.125” (nock to balance point)

3. Arrow mid point is 10.25” (1/2 length)

4. Difference between mid point and balancepoint = 3.875” (14.125” – 10.25”)

5. FOC is difference, 3.875” divided by totallength minus the BH/FP 20.5” = .189024.

6. Convert to % by multiply .189024 x 100 =18.9% FOC
