Aircraft Delivery issue
Description
I ordered 20 CS300's with Lead Time = 6.4 days Build Time = 3.2 days
Expected behavior: My understanding is that first aircraft will be delivered after 6.4 + 3.2 = 9.6 days. The remaining aircraft after 3.2 days each
Actual behavior: The remaining aircraft after scheduled 6.4 days apart
Is this behavior expected one ? Or should it be 3.2 days apart ?
