Understanding FOC and FACT

[@shitskadoodle]

Great video. I think it's carbon express that has muddied the waters about what FOC means in terms of arrow flight and accuracy. The other thing about FOC and why I like really high FOC (like >16%) is better penetration. A lot of the big game trad hunters rely on EFOC for penetration (combined with many other factors of course).
