Not sure how that plays into the discussion about the 9/10 ratio in the VCC video. Cards that were diamond cut, or printed with slight tilt or registration problems aren't going to be eligible for PSA 9 or higher anyway. Those all get weeded out at nice midgrade - maybe PSA 6/7 at best. The cards that they most notoriously control like the '80 Henderson and the '68 Ryan don't have sheet positioning or registration problems; I'm not sure about others.
