I would love to see someone take a comic to them, have 1 'expert' grade it (without slabbing it), and he/she would say 9.2. Then go back a week later, have a different 'expert' grade it (without slabbing it), and they would say 9.4, Then a third week, go back, and get another expert, and they would say 9.2. I would be willing to bet this would happen more often then not. Some of the differences are such minutiae, I could see it going down like that. But they created this mess. I think it has to do with time of day, who the grader is, what kind of day they are having, and blood sugar levels.
