Thank you. I will do my best on this front. It's obviously a detailed technical question that might certainly go beyond my expertise.
As was noted earlier, the issue of what particular shipments might enter at a particular border, a point of entry, and the nature of the risks associated with those shipments will define the level of intensity of activity. Now, there are two considerations, of course, that you note. One of those relates to the program design and the second relates to the level of delivery against that design. So the design takes into account the risk, the nature of products, and therefore you can appropriately see a diversity of that expectation.
