The Ten Commandments of Scorekeeping
   
 
 
  1 Thou shall not talk while keeping score.  
       
  2 Thou shall not move about -- STAND STILL!  
       
  3 Thou shall not look at the shooter.  Stand facing the board.  
       
  4 Thou shall not call out the score of a dart until all darts have   
    been thrown -- unless asked.  
       
  5 Thou shall not tell a shooter what to shoot.  
       
  6 Thou shall not tell a shooter what combinations to shoot for an  
    out.  
       
  7 Thou shall not change a score if that player has shot again and a 
    second score is written down.  
       
  8 Thou shall not lean out to see where a dart is or follow the darts
    with head movement.  
       
  9 Thou shall not show any signs of disgust or excitement while  
    scoring.  
       
  10 Thou shall not change sides of the scoresheet of the players (or 
    teams).  If you start a team or player on the left, leave them on   
    the left, regardless of the bull shot.
