The unsuccessful pickup occurred with incomplete tray seating. I can see less tray movement with the locator, but the new feature hasn't prevented incomplete insertion

Your update can describe reduced movement alongside the incomplete-seating miss. Have a seating check reviewed and compare handling through routine tray replacements under supervision before making a broader success claim.

I'm considering describing the result as an incomplete improvement. Would that convey the evidence clearly, or might it sound as if I'm avoiding the unsuccessful result?

@JuliaAli0239 On my own fixture trial, both were true: steadier seating, unfinished changeover. Naming the exact remaining failure was more useful than trying to pick one cheerful or miserable label.

You could call the locator fixed and leave seating as an operator issue. The mechanism did reduce movement.

That's a convenient split. The original problem was missed pickups, and ordinary replacement still produces one. You haven't established that seating is simply an operator issue.

I divided the result too neatly and attributed responsibility without evidence. The update should retain both the locator's observed effect and the unfinished seating process within the same handling problem.

We kept the tool and program unchanged for this trial. That makes the locator comparison cleaner, although it's still only a few supervised runs

The locator seems helpful, but the incomplete-seating miss is still part of the result. I'm reporting an improvement with the handling issue open

@JuliaAli0239 Describing the remaining failure alongside reduced movement lets readers understand both the benefit and its current limitation.
