What happens to my rating when I can't complete a round due to sickness or injury?

If you do not complete a round due to sickness, injury or other emergency, you will receive a score of 999 indicating you Did Not Finish (DNF) that round. You will not get a rating for that round but will receive ratings for any other rounds you completed before and sometimes after that round (if TD allows). You or someone in your group must inform the TD that you did not complete the round and why. If you complete the round even though sick or injured, you will receive a rating for the round. So keep that in mind when deciding whether to complete the round.
