I've kept the accepted and rejected FR10 trim-plate samples with their full images, but the lesson now points to different places on the accepted plate in two views, so I need the trainer to stop treating either bright line as a confirmed scratch.
Ask them to locate each arrow on the plate in front of you. We had a teaching image where the real defect was just outside the crop and everyone learned the wrong landmark. I wouldn't tune anything around those labels until quality has checked the actual regions.
