Quality decisions are attached to our retained covers now. Repeat pictures still wander because one rim can ride over the holder lip. I need a usable seating arrangement before these become training references (not another crop hiding the lip).
Have tooling compare that rim with the intended contacts using the retained covers. A repeatable image needs a repeatable seat, not a more determined person pushing the edge down.
Does that cover's rim differ from the others within the intended incoming range? The designer needs to know whether the holder must accommodate it, not simply remove whichever sample causes the repeat images to vary.
Within drawing, confirmed by inspection. Different rim shape within the allowed range. Designer is considering the contact arrangement, no change made yet.
Will the eventual comparison include the loader repeating the placement, rather than the designer carefully arranging each cover? That is where the practical seating uncertainty belongs.
