I have 30" Easton Jazz alloy arrows with a quoted straightness of .005" per inch, so a possible error of 5mm over the length. I bought 12 but they sent 14 (?) and I did roll them across the table and couldn't see more than 2mm, except for two which were clearly bent and are now repurposed. So with that visible, not theoretical, error can I expect to see a variation over 18 metres factored on the length of arrow and the target distance of about 2" from point of aim? I ask because I am destroying the 8's ring, which is 2" from the centre on a 40cm target whilst the 9's and the 7's have some action, the blue ring and the 10 are relatively untouched.
Is it possible to quantify the expected error based on the quoted arrow straightness?
