Interesting... I've never run into that myself. Might have to do with consistency of the thickness of the meat over the bones on the racks you're cooking. When the cutter trimmed the loin off the bone, it may not have been trimmed uniformly over each of the bones. I know that's why some racks have shiners. Maybe that's the issue? Or at least part of it? Sorry. Not sure.
