That's fair enough. I always say that if I was perfect I wouldn't be working here.
I do want to have a parliamentary review again, and I think three years would be appropriate, because the technology moves rather quickly. But I guess the difficulty we have now is that if it's 36 months it's hard to measure the business to business that's going on. So if we reduce that to, say, two years, how much of a compromise do you think that would be in terms of a stress on the industry, instead of the 36 months?
