The CSR is a global rating system for billiards based on the game history of all players.  It consists of two numbers: 

  1.     The rating (between 1000 (beginner) and 2200 (professional)) 

        2.     The accuracy of the rating (between 1 and 5 stars, the higher the better) 

Below is an example of the Rating you may see:
