There's got to other explanations for pressed books coming back with minor creases. Three of the last batch of nine Wolverine Limited, all pressed by Joey so I know that they were done right, have notes with light creasing to cover plus light bends added to one of them. These weren't the most pristine books (bottom of my Wolverine barrel) but six came back in the mid to low 9's and the ones with notes were 8.5 and two 8.0. The only explanations I can come up with are that the creases could only be lessened with a press, but not removed or the books were mishandled by CGC. The bends are another story.
