Add on another 5 feet and retry. To help 'read' the tear, one can smear some lipstick on the point, then they know for sure if arrow is tearing left, or tearing right. Sometimes it's hard to read where the point enters and where the nock leaves (on a bare shaft), the lipstick leaves its telltale mark on the paper.
Try this both with bare & fletched at 15'.
I've gotten my bares to tear about 1" maximum, they say a 1" horizontal tear or less, is perfectly acceptable. Now this is when my form and release are having a good day.
(They = Easton, IIRC)
Good luck to you
