    No, it doesn't take account of that. We've discussed that before at some
    point, and yes, I think it's wrong, but on the other hand, we want to be
    reasonably fast at deciding what to take, and there are a whole bunch of
    other criteria that we ought to be taking account as well - it's difficult.
