NGS for pairs event with substitute
In a club pairs on RealBridge, one of the players had to withdraw during the event after losing their internet connection. As there was a non-playing director, he substituted for the missing player for the rest of the event. The change of player occurred during the 6th of 20 boards.
Is there a way in which this event can be scored correctly for the NGS? The XML file from RealBridge seems to show the substitute playing all of the boards.
