I raised a similar spacer trial and still needed to establish how stores distinguished tray revisions. Worth asking here, but don't turn my unanswered question into your explanation.

And did the replacement bear against the locator in the same way? Matching outer outlines would not show the actual contact.

The sleeve was left in its pocket. I don't have a close view of first contact. We recorded which tray changed, but not its locating contact.

Then describe it as a miss after replacement, not a miss caused by replacement. That wording leaves room for a useful investigation without making the changeover operator the explanation.

I'd keep the earlier good runs in the report too. Finding a limitation doesn't mean the locator did nothing; it means those runs didn't establish the claim you were about to make.

Theo, agreed, but appearance of improvement is not a measured reliability gain. Keep the trial size and supervision beside it so the next shift doesn't inherit a production promise.

I have changed fixed pickup to looked more consistent in the supervised runs. Thanks, Luis; I also removed caused by the new tray from my draft.

A separate contact comparison can now be proposed without rewriting the earlier observation. Record the approved setup, tray condition and same-part repeat checks so you know which variable changed.

Who will capture the next supervised replacement comparison if you're not there?

Victor, include the supporting surface beneath the tray as well. The locator can be touched while the tray rests differently elsewhere.

I'd want the handover to say what remains unobserved, not just ask for more video. First pickup contact and tray seating are two specific gaps people can plan around.

The cell trainer owns the next supervised comparison. My posted update now includes the later miss, the missing contact view and the fact that we haven't confirmed a cause.

Has stores answered the revision question yet? It might simply confirm both trays are nominally the same, which would still leave the actual seating comparison to do.

The account is corrected even while the fault stays open. Keep any future comparison as a dated addition, so readers can distinguish what you knew after those first runs from what you learn later.
