The assessment is being done now. Of course, we always want to improve; this is not a stale system. As we go, the inspectors who participate in the assessments of the major carriers provide us with invaluable feedback, and using that feedback, and also in talking with the unions and listening to our inspectors, we will improve staff instruction.
But just to make sure that we're clear here, a portion—and it has yet to be determined, and it depends on the carriers and on the risk—of our surveillance activities will always be validation inspections down to the operational level.
I don't think it should be too random, though. I think we should use the tools we have acquired through risk management within SMS to better focus our activities.
