The hand histories are really what shows the chip dumping. In these HU sessions one of the cheats would
cap every street and fold either when he was down to his last few chips that would put him all in or for 1 bet on the river. Of course a nut player might play like this but a nut player is going to win a few hands along the way or get folded to. The dumper lost $55,000 in that session.
