If you are shooting such good groups out to 50 yards and broadheads are hitting essentially the same POI then I wouldn't bother with paper tuning. Paper tuning indicates how the arrow is leaving the bow, but farther down range is where the action is and I think you have a pretty good handle on what's going on "out there".

Take all the vital measurements for any future adjustments you may need to make such as brace height, A2A, peak weight, nocking point height and peep and kisser height from the nocking point. Also mark the side of the cam where it passes through the bottom limb so you will be able to tell if you are getting string creep (and if it's factory rigging you will have string creep over time).
