TLDR: If you are from California, the estimate might be now up to 11 days later than before.
Hi. I have updated the calculations again. I've changed the reservation percentages for different regions to the following.
Model 3 reservations by region:
21.48% USA, California
04.35% USA, Pacific Time States excluding CA
03.16% USA, Mountain Time States
07.47% USA, Central Time States
18.30% USA, Eastern Time States
03.33% Canada
22.80% Europe excluding the UK
12.59% China or Hong Kong
02.29% Australia or New Zealand
03.10% UK
01.14% Japan
@melindav. It turns out I was able to use the autoalliance data after all. Thanks again for the link. The reason I decided to use it is because I was applying some corrections to the service center count method. When I applied the same corrections to the autoalliance data, the results were very similar.
In case you are wondering what I mean by corrections, here is what I mean: From Q2 2014 to Q4 2016, Tesla sold 32,673 cars in California and 83,308 cars in the USA. Check out column Q and O
here for data sources. That means California sales were 32,673/83,308= 39.22% of USA sales. CA has 20 service centers. The USA total is 63. That's 20/63= 31.75%. You can see this in cell F3
here. I need to increase the 31.75% by %7.47 so it matches the 39.22% percentage which is the actual percentage. That means I need to decrease the service center percentages for other regions. The best way to that would be to decrease them proportionally to their existing value. Check out column G.
Autoalliance data needed a similar correction. It showed 52.24% BEV sales in CA. I needed to decrease that to 39.22% which means increasing the other regions. Again, the increase for each region was proportional to the existing percentage value. After corrections, both methods displayed similar results. Below, the first percentage is the corrected version of autoalliance data. The second percentage is from service center count method after corrections. The sheet now uses the average of these two methods.
