Default Scoring
If a pair is absent, or otherwise unable to begin or complete a set, their opponents are awarded a winning score (typically, 21). Any points scored by the defaulting pair will stand.
If neither team or both teams are at fault for an unplayed rubber, a figure of 0 should be entered into all six boxes in place of the score.
If single-set matches are played, the first set score is also entered for the second set (21-9 becomes 21-9, 21-9).
In the event of a disqualification, a score of 21-0, 21-0 should be awarded against the disqualified pair.
