If you do not complete a round for any reason other than manipulating your rating, and if you inform the TD that you will not be completing the round, 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). If you complete a round, you will receive a rating for the round, regardless of whether you were sick, injured, or otherwise impaired. So keep that in mind when deciding whether to complete the round.
