TFox,

After reading that thread, you are saying my best possible tune would come from:

1. Paper tune bare shafted arrows
2. Paper tune fletched arrow checking for clearance
3. Walk back test looking for arrows to fall straight up and down from 20 yards to 40/50 yards
4. Group test at furthest comfortable distance looking for best grouping

I've done 1 and 2.

As someone mentioned in the thread you linked in this post, couldn't I be even more accurate with the walk back if I shot groups at 20 and groups say at 35 and 50 perhaps? Or even just a group at 20 and a group at 40 until the center of both groups fall dead on vertically of one another? At which point I'd be very close left to right?

The group testing is pretty self explanatory, however, I shoota Mathews Dropaway and as far as I can tell ( might be overlooking something ) I don't have a micro adjustment for up and down. I do have one left to right, that being said, I'd have to adjust the nocking point to vertically group tune correct?

Thanks
