I appreciate your question and letting me re-articulate that. Perhaps, it was due in part to my not pacing myself well and missing some comments.
The point to be made in my notes was that was low-hanging fruit but it's critical and it's important and one must stay the course in terms of dealing with that. That is first and foremost. But having had some focus on that, it's now, whether it's lifting the veil slightly by that progress or it's simply that the other factors have become more apparent and we're seeing them now, and it may be a mixture, it's just the other more systemic factors are now upon us or becoming more apparent. My point was only that a doubling down on the cleanup of location-specific areas of concern was not an approach that was likely to get us back in this room 10 years later saying that we're doing well now on the systemic pieces.
In no way am I suggesting that we not stay the course and finish those cleanups. That was the priority and it was an appropriate priority. We need to stay the course on that. But now we have to recognize that just staying the course is highly unlikely to help us progress. You have to look to the science to prove this, but we're starting to see some of the signs that were referred to earlier. We saw a lot of progress in the 1970s, 1980s and early 1990s. Now we're starting to see plateauing. We're starting to see the re-emergence of some of the issues we talked about before, which I think overall is a signal that another step needs to be taken.
Thank you for the opportunity to clarify.
