Fun fact from Model 3 spreadsheet:
VINs assigned December 4-February 28 (~three months)=320. Average monthly rate=110*
VINs assigned March 1-March 20 (at time of post)=216 -- Monthly rate=335+
So assuming the spreadsheet data is representative, at the current pace in March we are on track to have triple the rate of VINs assigned compared to the past three months average. Also, triple the rate in February (109 VINs in a short month), and almost 2 and 1/2 times the rate in January (141 VINs).
Together with the increased VIN registration rate and decreased time from registration of a new VIN range to VINs being reported in that range (down from 4-5 weeks to about 2 weeks), this seems to support a significant step up in production after the Feb. 20-24 shutdown.
The one lagging indicator are deliveries, which do not yet reflect a dramatic increase. I think this is likely explained by delivery lag times to the East Coast and that we are about to have a large volume of West Coast deliveries, but we'll have to see.
