RE: can someone run these #s in ontarget please
Sort of on line with what Paul said, make sure you're comfortable with the maximum draw weight of your bow, try to get your arrow spine to land in the middle of that range, then use the ability to fine them throught adjustments in arrow length, tip weight and draw weight. If you can handle the full draw weight of your bow, you are limiting it's usefullness to fine tune arrow flight.
OnTarget might get you close if you have a crono'd arrow with the stats to put in the program. Without the manually obtained crono'd speed, I wouldn't rely on anything it gave you. It's pretty easy to confirm through bareshaft testing.
