I'm all for re-running it but I can see your point Andy, the rule book states-
19.3 At abandoned events where less than two rounds of qualifying have been completed, the event will be declared null and void and no results declared. Such events will not be re-scheduled and any relevant championship qualification will be reduced accordingly i.e. if there were four rounds to count from six, then one abandoned event would mean there are three rounds to count from five, etc.
Am assuming this is for Regionals and Nationals and not just Nationals?
