I must have been fortunate for in my 20 yrs of dancing I always found the judging to be fair as long as there were an odd number of judges. The spectators always seem to know who the winner is and this keeps the judges honest. It's difficult for the judges when competitors are equal in ability or are all mking the same mistakes as they will be when all dancing at the same leval. Sometimes a shining star will arrive and dance quickly through all levals.
