I mean, I'm not sure how you come to that conclusion. Shanghai already averaged 1716/day from the upgraded Y lines. They didn't do 1716 on Day 1 of the start of the lines. Meaning the exit rate for July was already at 2,000. Which puts Aug Y production at 62,000. If they were able to get the lines up to 2,000 Y/day in just 2 weeks, why wouldn't they be able to hit 2,200/day for most of Aug? Which would then up the Y production for Aug to 68k.
Then take the 3. The goal is to get the 3 lines to 1000-1200/day. If the 3 lines follow the same ramp as the Y lines did in the first two weeks, they'll average 800/day which is 25k for Aug. Thus, Aug production in total will be 68,000 + 25,000 for a total of 93,000. Even if you discount the rates some, you'd still get a production number much higher than
@The Accountant for Aug and thus, he would need to update a lot of numbers in his spreadsheet.
Maybe it's because of the Covid shutdowns and then the line retooling, but it seems you're just ignoring what the numbers are telling you and assuming the worst. Yes there could be something that comes up in Aug or Sept that reduces the production rate at any point, but before the Shanghai covid lockdowns, the Shanghai factory was incredibly consistent on production levels. So if they're hitting those production numbers already after the Y line upgrades, well then I go with them consistently hitting it.
