Testing Compactrons

I've been testing a box of tubes I have on my newly acquired B&K 667. About half are compactrons. A couple of them have one side test a lot higher than the other. The low sides test barely in the green, the other tests about in the middle.

Do all the sections of one tube need to test nearly the same to be keepers? Or, is it acceptable to have one a lot lower than the other?
