I think I would have got the same results with On Target if I'd just changed the IBO speed to get the predicted speed to match my chrono'd speed. Instead of using my bows advertised IBO of 316, I would have put in 298 for the IBO speed. The arrows that spined perfectly at a 316 IBO would have been overspined if I changed the IBO to 298, correct?
My trial version has expired, or else I'd try it to verify.
You would NOT have got the same results. See my previous post. Changing the performance slider does not give the same arrow spine result that you would get by changing the IBO speed. IMO changing the IBO speed gives you the result that actually matches your bow AND arrow setup.
