Ranking Attack Roll Margin of Success

[JCurwen3]

Social Engineering, p. 31 has Expanded Influence Rolls. It ranks MoS for Influence Rolls as follows:

Margin of Success Reaction
+8 or more* Excellent
+5 to +7 Very Good
+1 to +4 Good
0 Neutral
-1 or -2 Poor
-3 or -4 Bad
-5 to -7 Very Bad
-8 or worse Disastrous

Is there a ranking in RAW or somewhere on these forums that's appropriate to rank the success of attack rolls? Or would someone like to suggest one? I think this could help to describe how good the hits of enemy combatants were, while still being able to roll their attack rolls in secret and not reveal too much about their actual skill levels.

It would start with 0, which is just hit. In Pyramid #3/34: Alternate GURPS (p. 28), T Bone suggests considering them grazes, including effects like halving damage and doubling opponent DR. I use and like this rule.

Aside from MoS 0, I guess I've never kept track of MoS for attack rolls before, and am not sure how high they can be between two reasonably competent combatants.
