This is not as relevant as it used to be with the recent rules changes off extra trades and DPP additions giving the ghost ship team little chance of winning the comp (like it has previously). However this is the best score achievable for a team that was set and forget after round 1 with an emergency set on each line.
Note this score of 54,623 (avg 2276) is some 2,761 points behind the winning score of 57,384 (avg 2391) and would have placed around 6600th.
