In over 5 years of testing we have experianced on average 75% or more Dynamic Arrow Tuning Tool flex indication success. On average we see up to 3 arrows out of a dozen that are what we call "Inderminate". When group tuning after our initial arrow build process, we end up turning very few nocks, but those that need turning are more likely than not already marked as "Inderminate". Occasionally we cannot get an arrow to join the group even with nock tuning consistantly and remove it from our quiver. Although many have called this a "spine tester" we consider it much more than that as so many different factors can effect the dynamic flex of an arrow. From seam placement, straightness tolerance, shaft squareness, to bushing fit and how they all amplify or counter act one another as a whole.
