There are many small details in tuning that can help if addressed and corrected. However, for most shooters tuning the bow and arrows is a very small part of accuracy. I think that arrow flight is important for hunters since it is a part of good penetration.

But for accuracy, you only need a bow that you can shoot and well matched arrows. The arrows don't need to be precisely matched to the bow, just matched to each other andapproximately matched to the bow.

The most overlooked aspect of tuning? IMHO it's nock straightness. When I got a tool to precisely measure nock straighness, my league scores increased by almost 10 points. I won't tell you the exact numbers, but let's just say that I still have an opportunity to demonstrate the value of self coaching

In Roscoe's first post of this tread, I don't think that a half turn would account for the improvement in group size. Perhaps he hit on a sweet spot in his draw length. That may account for the improvement, but I don't think that much improvement can be attributed to fine tuning arrow spine unless there is something else going on with the bow, such as fletching contact.

I do agree with WKB Todd and Tfox about the loose nut on the release.
