My 452 grain arrows drop 2" between 20 and 25 yards, I've tested that time and time again at the range with fixed and mechanical broadheads. I shoot 29" arrows, 63 pounds and 29" draw. How could that be if a 30" draw, 31" arrows and 70 pound bow would drop 2.5X that? Exactly how perfect is your data?

The example which you quoted was for a responders bow who draws 42 pounds to 26.5 inches. I based the arrow drop on his chronographed arrow speeds.
Good hunting.
