Hmm. I kind of suspect those numbers for the X are way off. Our sheet shows the average in the past for order to delivery is 395 days for an LR (or about 13.1 months). If you look at unfulfilled orders the average wait time so far is 381 days (12.7 months), so the wait time doesn't appear to be on track to be dropping significantly. Of course there might be a lot of recent orders that aren't accounted for in the sheet, but there is no indication that they will be delivered any faster than the older orders. Maybe once they run out of plaids they will increase LR production? But i doubt that makes that big of an impact.
Edit: Ah, looking again, he is taking the Tesla EDD for new orders at face value. We all know how good Tesla is at generating EDDs...
