Guidelines for the Scorekeeper
Do not talk, drink or smoke while keeping score. 
Do remain still so you're not a distraction to the darters. 
Do not look at the shooter, but face the board. 
Do not call out the score of any darts unless asked and do not offer strategy suggestions (even when the darter is obviously shooting at the wrong out). 
The scorekeeper may inform the thrower what he has scored and what he has left, when asked. 
Do not change a score if the darter has shot again and a second score has been written down. 
Do not record any bounce-outs as a scoring dart. 
The score of a dart is determined from the side of the wire at which the point of the dart has entered the board. 
Do not show any signs of emotion when scoring. 
Always keep the darters on the same side of the scoreboard, for all matches, no matter who wins the diddle or who is starting first. If Team A is on the left hand side of the scoreboard for the 1st game, then Team A should be on the left hand side of the scoreboard for all remaining games.
