The extra locator made our FR10 housing pickups look much better, but we still missed after changing trays. So my draft update saying fixed is going in the bin. Same trial, one promising run and one awkward counterexample. I'd rather post both.
No point edits. I've rewritten it as better pickups on the first tray, miss after replacement, tray differences still being checked. Not the triumphant update I had in mind.
It is still useful to someone trying the same thing. Include the observed run size and whether you reseated either tray, so they know what the better result actually covered. You don't need a victory announcement to report a worthwhile experiment.
