But as others have said, it's a pretty poor diagnostic and lots of things can cloud the issue - things like the type of abrasive particulate and the shape of the scratch it leaves, and how that shape reflects light back to your eye. A sharp particulate like diamond chip may leave a "V" shaped scratch, whereas a more obtuse particulate might leave a flatter "U" shaped scratch, both at the same depth say. One may well look worse than the other under reflected light.
I dunno, that's just random thoughts. Sounds pretty good though, right? :)
