You've said that we have to do a whole bunch of things, but if we take any particular element and we redouble our efforts, what is a reasonable way of setting a target that isn't in la-la land and that takes into account the unforeseen?
I'm just asking how one...because we do this all the time. I mean, all of what you do is about setting targets and meeting them.
So are there things the government should be aware of when it sets the new target?
