I agree the black flag was pretty silly the first time out. Like Jerry said, there were 4 or 5 of us w-in 1 second of each other and there was no way in the world to tell who the flag was for. It wasn't until the second lap around that I saw the number board.
It would have been more beneficial if they had attempted to point the flag at the individual. Everyone knew the black flag was out, we just initially had no earthly clue who it was for.
