If bare shaft was good and fletched isn't.........your rest/set up needs fixed.
Weak is nock left for a righty.
Overspined can crash riser and kick for nock left too.
This is what is known as a "false reading".
Paper tune works, but only if done correctly. It should show you the same stuff bare shaft does.
Bow quivers can change tune and really screw things up if too far fwd. A bit rearward is better.
Standard stuff. Not rocket science.
But if you get flustered and start second guessing this and that, peek in shooting.............youre just gonna make a mess of it.
Relax and start from scratch.
