this is from a post of mine on a similar subject
came from link to dr daves stuff from bob jewett
the rating system i like is this
from phil capelle
Here's an alternative and more-detailed interpretation of the A-D scale from Capelle's "Play Your Best Pool" (p.386):
D: A beginner or someone who plays so infrequently that their game remains in the beginner category.
C-: A below average player - this denotes a player with some recognizable skills who has definitely risen from the ranks of beginners. This is the first major milestone.
C: An average player - describes a large section of pool enthusiasts with experience whose games perhaps have leveled off, or that only play occasionally.
C+: Above average player - this group plays a very acceptable game of pool. They tend to dominate their level of competition.
B-: This is perhaps the biggest hurdle, as a good number of players peak at the C+ level. A B- is a good player who is quite capable of running a rack of Eight Ball or Nine Ball. However, they usually lack consistency.
B: A solid, advanced player - these players can run out fairly regularly, but lack a little consistency.
B+: Players at this level are often mistaken for lower level A players when they are playing well because they play a very tough, well-rounded game. They can run out from nearly anywhere at anytime.
A-: Another big jump is required to break through to the "A" level. This group of players could be classified as semi-pros or top amateurs. They are very skilled in nearly all facets of the game. They run out easily and very often.
A: A professional quality player who can compete with and occasionally beat all but the best players. Very skilled, solid, and consistent. Runs multiple racks quite often. Tough to beat.
A+: Touring Pro - the best. Skilled in every area of the game. Breaks and runs out multiple racks regularly. Definitely in a class by themselves.
So using this rating system…. where would you put a player like… Shane McMinn or Danny Smith (Playing 9/10 ball)?
