PSA Grading really reliable?

[Leon]

LOL...

But to the first question, are PSA reliable graders? PSA isn't a grader; some unknown person is. So, they might be reliable and might not be. Grades are only an opinion at that moment of that grader's mind. It could be a half a grade either way, almost every time. And many times, more than a half grade difference, on the same card (*and maybe by the same grader at a different time.) "Reliable" is sort of subjective.
