I was finally able to get out and shoot my new bow. IBO is rated at 360fps, I know this is at 70lbs, 30" draw and 350gr arrows. My setup is 70lb, 29" draw and 420gr arrows. I shot my bow through the crono and was getting 310fps. I think I have seen a calculation out there to figure out what my specs would reference to if I was at IBO specs. I was able to figure out that I am getting 89lbs of KE wich I am very happy with and my FOC is only at 10%. I read that 10% is on the low side, should I be concerned with this at all.
Thanks
