In a post I made a couple days ago, the weekly registration numbers as of Sept 18th totaled about 44k. That meant to hit 100k, they need to do 56k in the final two weeks of Sept. If Tesla China follows the same pattern as Tesla US does in its delivery logistics to make sure all production is delivered, then the final two weeks of the quarter will see 25-30% of all deliveries for the quarter. That’s because in the final two weeks of deliveries, you have vehicles being delivered across the entire United States. Vehicles that had been in transit to the East Coast, Midwest have reached their destination points at the same time more recent production is being delivered on the West Coast. And then finally in the last week of the quarter, California gets flooded with deliveries. If you apply that to China, then 56k in the final two weeks is entirely possible.
Bare in mind, these weekly numbers are not official number and someone should probably go into that persons tweet history and line up if the weekly registration numbers actually are confirmed when the official CPCA numbers come out.
