This is what matters. You're consistent and to be completely honest 268 is plenty fast enough for a hunting rig. I'm pullin 74lbs and shooting basically the same as you 270 fps. If you can hit your mark thats what counts.

I feel too much emphasis is put on speed. It's another gimick the manufacturers use to sell high end bows. If it weren't in the formula for ke I would even chrono my bow. Your bow is fine and as you'll see this fall, very lethal
