Thank you for the question. It's one that the Cohen inquiry is looking at, so I will not try to guess where they will go with this.
The scientists themselves are the first to say that what they can do is provide, based on certain facts they have, a range. They're never comfortable giving a pinpoint estimate, but given all of this they're often pushed into giving the pinpoint estimate, and that's when we're generally wrong. When we give a range, that tends to be generally correct. We tend to fall within the range, but it's a broad range, and it's not a range that people find very interesting, because it's too big. But it is based on the science as we know it, and it's based on us recognizing that we don't necessarily know what happens or where they go when they go out to the depths of the ocean.
We can predict what happens based on what goes out and on the conditions when they're coming back in but not on what happens when they're in the ocean.
