Default Tuning Confusion

Let me start by saying I don' t paper tune or bare shaft tune, BUT I DID. I group tune and my groups seem to be fine, but I' m confused with the results of my paper and bare shaft test. My setup for 3D:
Right handed, caliper release, loop above and below nock (No nock contact)
Martin MV2 with fury X cams (split cable).
28-1/4" amo draw.
58#
Creep tuned to 40 yards.
27.5" cxl 250, 80 gr point (little stiff according to archers advantage)
Bodoodle pro-lite (spring tension as advised by Bodoodle)

My results:
paper = 1-1/2" level right tear
Bare shaft = 8" left 5" low bare shaft

Bare shaft left indicates stiff shaft. Easton says right tear for right handed release shooters is uncommon and indicates possible vane contact. I powder tested and no contact. I increased bow weight from 58 to 64 pounds. No change in bare shaft or paper. I decreased to 53 pounds. No change in bare shaft or paper. I moved nock higher, No change in paper, bare shaft didn' t move left or right but moved closer or further apart depending which way I moved it. If I moved far enough down to get bare shaft close, I am below level (nock low).
Changed to a longer weaker arrow (29" ). Same results as above. No change in paper tear. Very minor (1/2" ) change in Bare shaft left result.
Moved rest to the left. No change in paper tear, but bare shaft moved closer to fletched. I got them even in the vertical but they are still about 5" apart (bare low) when I have my nock about 1/16" above level. Problem with this set up is my powder test shows my center shot too far left. Everyone with fury-x cams say their center shot is perfect center.
What is my bow trying to tell me? I will ignore the paper and bare shaft unless someone will convince my something otherwise. I shoot plenty. My 34 year marriage probably won' t survive 1 more arrow than I shoot now.
Any help?
