Not sure whether adding the wheels and the time of the year they do some heavy duty scheduling either side of the Christmas shutdown have added up to a wholly unrealistic planned BW, and it may drop back down to something reasonable like BW6, seeing as it was up to BW8/18 before even adding the wheels. Maybe it's down to my order being flagged as not required until February on my order form (for a March delivery). Who knows, i'll wait it out, my GTD isn't a bad place to be right now - although the winter mpg is utterly sh!te, averaging about 41mpg indicated.
