Totally misread the title and was thinking December deliveries, which inside ev's guess of 1060 makes me feel good about the number.
Overall I think things are fine, ramp seems to be about 3x each month (so far). Should be about 3000 January, 9000 seems like a stretch for February but I could see it doubling after that to 6k in February, 12k March, and ~20k a month by April.
