Paper tuning questions

[inthere10x]

First time trying paper tuning. I feel my arrows are flying good, but I like to tinker. My son was rolling his eyes when I said "we" were trying paper tuning.
Set up: target was 3' behind paper stand and shooting was done at a distance of 12' and 16'. Set up ok?
How "clean" should the hole be?
Please critique the below holes (if I can get pictures to post)?
 
Above shots from 16'.
 
Above shots from 12'.
 
Above Erik's shot from 12'.

See what they look like from 6'.  From the bottom two pics, I'd say you need to lower your nock point a touch. However, the same type of tear can result from a couple of other things, too. Namely a too low of a nock point, or a too high string arm elbow. Both will cause the arrow to bounce off the shelf.

Have you tried bareshaft or broadhead tuning as well?

Yes, I normally use the bare shaft/broadhead tuning method. I was tinkering with something different, trying to "tweak" my set up.
My current nocking point is 9/16" and I'm shooting Gold Tip 3555 arrows.
Looper, I only need to be 6' from the paper?

Yeah, only about 6 feet. If you are too far from the paper, the arrow will have time to stabilize.

If you don't already, I'd also recommend adding a second nock, one under and one over the arrow. Make sure to leave about a 1/16" gap so your arrow isn't pinched at full draw. The reason behind the double nocks is that your arrow slides down the string upon release. That also results in the arrow bouncing off the shelf.

I like close, too, 6 feet  maybe 10 feet at the most.  Fletching can start steering pretty fast.  Looks like you are just a touch nock high, a 6 foot arrow will tell for sure.  Spine looks good so far.  Form can make a difference, so try to do your best with that and ignore tears different from the others.

I like to shoot a bareshaft through paper, starting at 6 feet. Then when I get a clean bullethole, I go outside and shoot 10yards, tweak it if needed, then go to 20yds, tweak if needed, etc.

If you're shooting fletched shafts, I would imagine you need to be close to the pape as mentioned because the feathers will straighten the arrow rather quickly.
