Q3 production was 20% above Q1: 1.2*1.2 = 1.44 or a 44% extrapolated growth rate over 4 quarters. Upgrade shutdowns were in Q3 and were not finished until mid August and mid-September. They had to recover from lost production with the new capacity in a sub-quarter time span.Q2 was an outlier though. Look at it like this: Q3 2022 was only 11% higher deliveries than Q1 2022. With two new factories ramping plus production upgrades in Shanghai I think many expected a higher increase in 6 months than that.
FWIW: 6 month growth of 22.5% yeilds 50% yearly.
