I don't think we can have a single benchmark for every area of the law. If somebody is about to lose their liberty, or their house, or their child, that may require a different threshold than some other kinds of problems. I just look at it that way. I think it has to be issue driven and consequence driven, because that's where the net saving is going to be. If you get it right at the front end, you get the most savings.
If somebody doesn't lose their house, doesn't have their child taken away when they shouldn't have had their child taken away, when other services could assist their family, that's when you realize the most benefit. Maybe that would mean that the threshold is higher, for example.
