I have really tough time following logic of some questioning the official guidance from the company, but not really showing conclusively, why it is not to be trusted. I do that sort of questioning of the information coming from the company all the time. And every time I do, I always readily find information to disprove my own skepticism.
Take the discussion about whether there is or there is not a 50% growth in orders (i.e. reservations) YoY.
So lets dig a little to bring clarity on this question.
The latest
update on the wait time that changed deliveries for S85 was on 02/27/2015. The wait time was from 02/27/2015 to May. Assuming first week of May yields a minimum wait time of 11 weeks. Based on the production rate of about 1000 cars/week the total backlog was approximately 11,000 cars.
Going back 1 year, based on several posts in Model S delivery thread (#6352, 6357, 6368), the wait time was about 7 weeks. According to
Q1 2014 shareholder letter the production rate at the end of Q1 was 700 cars. So assuming no further increase of the production rate within the wait time, the total backlog was 700 x 7 = 4,900 cars.
So production grew approximately 54% Feb 2014 to Feb 2015. At the same time the backlog also grew, by a whopping 124%. So not only demand is well ahead of the 54% ramp in production rate, it is in fact outpaced ramp in production by huge margin.
There is no question that Company's claim that demand outpaces increasing production is true.
