Why Tesla Model 3 production seems a little low

Tesla just reported their Q3 Vehicle Deliveries and Production results for the Model S, Model X, and Model 3. This was apparently the company's all-time best quarter for deliveries on both the Model S and the Model X - by just a tiny bit - at a 4.5% increase over this same quarter in the year 2016. Quarter-by-quarter, though, Tesla's production rose a cool 17.7% (over Q2, 2017).
