In the mean time, this has a lot of the same info as the Easton tuning guide...

Make
small adjustments. Once I finally got mine close to perfect, it took some rediculously small changes to get it dialed in just right. A 1/4 turn of my limb bolts changed my bare shaft point of impact 6 inches at 30 yards, and put them right in with my fletched arrows. I had been making too big of adjustments, and kept overshooting the sweet spot. Also, you want to shoot bare shafts only when there is no wind.
I find that I get more easily readable results from bare shaft tuning at longer distances. Under 20 yards, it seems you can get false readings depending on your target. If bare shafts are hitting close to the fletched ones right away, then grdually start shooting them further. They really don't start planing a lot untill 30 yards. They can plane pretty badly though if things aren't right, so start in closer and work out to 30.
