to guage yourself without a lot of hassle:
Never run a 9 ball table, D player
Have run at least 1 table, C player
Have run a 3-5 pack, B player
Have run an 8 pack, A player
Have run multiple 8 packs or better, A+ player.
There you go, simple, to the point, easy to remember.
I think this is a bit excessive. A players speed has more to do with an overall game then how many racks they have strung together. Its real easy to talk about an 8 pack on the internet, but I think it happens a lot less than its talked about.
I think a better way to judge speed is either the joe tucker system that was posted by tjlmbklr
or
Something Jude posted a long time ago that seemed to make sense.
"D - Will appear as though they are stumbling through the rack. Their occasional run-outs will either consist of very easy layouts (which they will nearly mess-up), a few lucky shots and/or unintentional position.
C - Greater sense of cue control and much more of a deliberate appearance than a D. They will undoubtedly run out with BIH with 3 or 4 left and will make it look routine but are suspect beyond that.
B - Really the beginning of the run out player. If they make a ball on the break and get position on the 1 ball, they should have a reasonable expectation to get out. Any cluster or unusual position play will diminish their chances significantly. Usually, B players possess unusual strength in either pocketing, strategy or position play. Rarely two of three, never all three. Their creativity is usually limited at this level but you may begin to see glimpses of what's to come.
A - Definitely catagorized as a run out player. They are supposed to capitalize on most mistakes. Greater attention is paid to more subtle details. Expect a consistent and strong break and strength in multiple attributes (pocketing, defense, position play, creativity). Most noticeable among players at this level and above is an aura of confidence.
Open & Above is very similar to what you see described in A only more refined. You will see advanced to expert break, pocketing, defense, position play and creativity. Low level opens might be advanced in all of these catagories while world class professionals might be experts in most or all. All of these players are expected to run out with any routine opportunity. Any run-stopper situation (clusters, blocked position routes) is expected to be handled in such a way to still give the shooter an expectation of winning."
