If these extra boards contributed to a more balanced distribution of black and white, we will cancel the 5th (and the 4th) board and use the result in the new boards. For example: if in Board 1~5 player A is always assigned Black, and in Board 6 and Board 8, player A is assigned White while in Board 7, player A is assigned Black again, we will use the results from Board 1, 2, 3, 6, 8, instead of Board 1~5.
