Purely conjecture on my part. but if I were Elon I would:
1) Focus on getting Model Ses our the door for the end of the qtr, since, presumably, they have that down to a science and Model Xes still take longer, they can hit their volume target and keep Wall St happy
2) Let the Founders live with their cars for a couple of weeks as a final quality check
3) Slowly start ramping up Signatures by mid October if the Founders cars are not imploding. I think to keep the analysts happy, they need to reasonable volume of the X by end of Q4, at least 250/week
