Re: Catagolue Oddities

The twenty-ninth most common object (Big S) apparently has only appeared eleven times in C1 . I've seen Catagolue not mention any soups if an object is too common, but I've never seen it give a falsely low number before. This is related to apgsearch not generally reporting sample soups for very com...

Wouldn't that also imply a new P550?
EDIT: P510
There's already a smaller p510 in the collection:
