Am I A (Grading) Thread Killer Here?

I agree with Mycrob that it is helpful to describe how one arrives at the estimated grade. The major grading services use some kind of team grading process to come up with the final number that goes on the slab. I presume their graders have to discuss their grading rationale whenever there is a significant grading disagreement.

I always try to mention the specific features that contribute to the grade opinions I post. That way, if I'm off the mark you can at least see how I got there!
