You may have helped me to understand one of the things that I found troublesome, which is on page 9 of your report, which indicted that the management team had proposed the question on how effective the barrier is, and the answer was that a detailed evaluation of the effectiveness of the barrier was not conducted in this risk assessment. From my perspective, that would be the first thing to do. I would want to be sure that the barrier was effective.
You're indicating that the problem hasn't reached point 7 yet. Is there any other way to examine the effectiveness of that barrier, in a theoretical way at least, or give us some assurance about how effective that is?
