Their revenue isn't supply driven anyway, it is demand driven. Two weeks of delay will not result in 273M in lost sales. It will just result in delayed sales.
I know two people who withdrew their Tesla Model 3 reservations due to them failing to meet a deadline. Their reasoning was that they'd like to buy a Tesla, but if they need to wait years for it, they prefer to get a nice car to drive in the meantime. The longer the delays are, the more people will give up.
Anyway, Teslas are overpriced and of questionable quality.
If I am 100,000 in queue, then car should have originally taken 20 weeks at 5000 cars per week. Now it will take 20.62 weeks at 4850 per week.
That is a delay of few days.
You're quibbling over a rounding error.
