I also posted a link to the site that had all armor types listing NR in the G-doc, if you want to relink it in your stuff.
As for the 9% hit, right on spot with the scope+2h+zg. If one were to keep that high NR list, you can easily drop a ring for a AV ring, or as horde 1 of the trinkets for the hit trinket from hinterlands.
As you mentioned with the list you made, it is well over the unbuffed mark, but you can go even further if you included lower armor types (leather and cloth) and Amulet of Foul Warding (extra 20 nr). Though it's way overkill, there is possibility to reach cap unbuffed.
