It's hard to tell you on the spot. We've done a plan of work for 30 regulations to cover more than 80% of the use in three important sectors. To understand what “significant” and “increasing” applies to and to determine how many more regulations that would be, and then to try to figure out a compressed timeframe.... I admit I can't do that on the spot.
It's possible we could do it in less than four years, but I wouldn't like to guarantee to this table that we could do it in two years or even three years.
