Yes it is decided by lots of factors but foc isn't in the equation.Atleast within the parameters of the archery industry it isn't.


Ask anyone who sets up sight tapes for their sliding sights,they never have to worry what the foc is,the total weight and drag are the deciding factors.All my sight tapes have been accurate to 80 yards when I get the info right.I just ran some settings out to 70 yards with 2 different foc's and the clicks were EXACTLY the same as well as the total drop of the arrow.


One of the programmers for an archery program was on here a few years ago arguing this very point.
