Okay, here's my question (coming from someone with little to no experience in grading, but I am trying to learn how): So, you guys are saying 9.4, 9.2 by looking at the scan of the front cover; how much do you have to factor in the back cover and internal pages when grading a book? Stains, rips, color, etc.?
In my opinion, when it comes to grading, the back cover is just as important as the front cover. When it comes to appeal, however, the front cover is obviously more important since it's the part of the comic that you will see first.
For example, if the comic you have pictured above (UXM 266) has a huge piece (1" - 2") missing from the back cover, the grade would drop considerably (probably down to a Good or Good+) despite what the front cover looks like.
Likewise for the interior pages, although very small defects (like tiny ink blotches, very, very small tears on the page edges, dog eared corners that do not tear, etc.) are more often overlooked than they would be if on the front (or back) covers... especially on mid-grade or slightly higher books.
Like I said, this is just my opinion. All people will grade a tad differently than one another and give more weight to certain defects than others would based on personal preference, but I think I'm in the ballpark.
If you get the chance and haven't already, give this book a look:
I was able to check out a copy from my local library and look at it before I went and bought my own. It really helped me a lot when I started the grading part of my return to comic books.
