WebOct 23, 2011 · A higher FOC arrow has a heavier tip, this in turn generally requires an archer to use a stiffer spine and this stiffer spine always results in less deflection. Additionally the closer the center of balance is to the tip of the arrow the more force it takes to flex the shaft upon impact this effect is realized regardless of static spine. WebJan 21, 2024 · You might like the FOC calculator but also want to learn how to calculate FOC using a formula. The formula to calculate an arrow’s FOC is: 100 x (Balance Point measurement [A] – Arrow Length [L]) / 2.
