Mike,

No there should be no accuracy problems with slight variations in FOC. In fact I have shot fixed broadheads down around 8% and target arrows in the 6% range without any problems. There is a wider range than most archers think shooting a compound with a release and shoot through rest. Besides a calulated FOC there is an effective FOC to most arrows. This is due to the increased drag on the aft of the arrow as the velocity increases giving the arrow more dynamic FOC. A lot of it also has to do with the arrow being correctly spined, your bow being tuned well, good shooting form and you can widen the parameters a bit. If you take your time you can take the measurements on your arrow and do the raw computations for yourself. Its really not that hard to get the balance or FOC point. Personally I think Steve Jackson's calculator is adequate enough.
