I don' t get all hung up on the straightness tester for my arrows because I can' t measure the spine and how they are going to react when shot.

My newly aquired Beeman ICS Hunters, after I properly installed broadheads and inserts and spun tested them all grouped within 4" (shot at individual spots) at 40 yards. Considering this was nearly as good as I could do with field points on my old bow I was pretty happy. New bow and these same arrows group less than 3" and I shot off two nocks and ruined 5 fletches before switching to 5 spot targets. Not one of the arrows of the dozen failed my group test.

I ran them through the straightness tester and discovered the best arrow was .002 and the worst .007 after each of them had been fired over 50 times.

Groups matter for me and none of the dozen failed.
