when we run a '299 tourn, we do NOT use human subs for a sitout since they do not get screened for MP limit. (it took a while for us to realize that the subs in a '299 could be super life masters). so, what we do: 1) sub robots at beginning for the sitouts 2) each round, ask opps if they would rather play against robots or have a sitout 2a) if robot = no problem, then play on 2b) if do not want to play against robot, then do nothing. When board(s) times out, score will become A== AND, as others have noted, robots might finish 1st (2nd etc.) but are discarded from score before masterpoint awards are given.
