They paper tune at 5 ft though… my gut says needs to be paper tuned further out .
How far is too far to do this. I am bareshaft testing right now .. trying to be OCD about arrow flight as will be using single bevel heads vs mechanical
5' is a good distance to paper tune with a fletched field point (FP) tipped arrow. Fletching corrects the flight so quickly with a field point on the end that much further than 5' to 6' and you won't see how the arrow is leaving the bow very well, the fletching is already correcting it. 5' is a pretty commonly used distance for most shops, assuming they're not tuning with a bare shaft arrow.
With that being said, it sounds like someone at the shop shot the bow during paper tuning? That doesn't do a great job for you, as you likely have different shooting form than the Tech that shot the bow.
Paper tuning at 5' with a fletched field point tipped arrow is a good starting point. It is only a snapshot of what the arrow is doing at one single distance but normally gets you close enough that the final tuning can begin. It can be close enough for shooting FP's, but may not shoot well once a fixed broadhead (BH) is put on the end. The blades on the front of the arrow try to steer the arrow too, and it takes longer for the fletchings to correct the arrow flight since they are "fighting" those planing blades on the front end.
Your bow tune may still be quite a bit off if your shooting form is quite a bit different than the Tech that shot the bow. Hopefully it is close enough that just a bit more slight adjustments are needed to finalize the tune.
You do need to get your sight adjusted so you're hitting closer to point of aim (POA), just to ensure you don't miss the whole target. But hitting to the right at 10 yards may or may not indicate the bow tune is off. If it is a new to you bow setup, it is common for the sight to be quite a bit off when first put on the bow. You mentioned thinking the arrows are flying nock left since you're hitting so far to the right, but it may just be that the sight simply needs adjusted. It is pretty common for a sight to need quite a bit of adjustment when it is put on a bow for the first time, whether the sight is new or coming from a different bow setup.
At the point you're at, I would get the sight sighted in with FP arrows at whatever distances you want, then move to checking the tuning of the bow a bit further. The bow tune is probably plenty fine to get sighted in. If you find that you're running out of sight adjustment in one direction when sighting in, then I would worry more about how far off the bow tune may be...or how much it may be your own shooting form causing it. Only worry about that if the sight runs out of adjustment.
