Xpeng exported 450 cars in the week from Jan 29 - Feb 4?

Xpeng Jan delivery was 8,250. This dictates 1,450 registration from Jan 29-31, as there were 6,800 registration from Jan 1 -28.

Feb 5-18 registration was 1,000. Feb 1-18 registration was 1,800. This dictates 800 registration from Feb 1-4. Total registration from Jan 29-Feb 4 is 1,450 + 800 = 2,250.

2,700 registration was reported from Jan 29-Feb 4 which is 450 above the 2,250 calculated above. Is the difference 450= export?
