Originally played over three evenings, the best two scores of each pair were added together and then listed in order of merit.  The top fourteen pairs played over two nights for the Club Cup. The next fourteen played in the consolation event for the Harry Stein Trophy and the rest of the remaining pairs were out of the event.  Entries began to dwindle so the old format became unworkable and the competition changed to run over four nights.  The best three scores were added together and listed in descending order to find the winners of the Club Cup.   Handicaps were then applied and the top scoring pair after applying the handicaps were winners of the Harry Stein trophy with the proviso that the winners of the Club Cup were ineligible to win the Harry Stein trophy.
