Yes, and I'll echo a lot of that.
Another thing, for example, is that for universal call blocking, when we first implemented it we kept the net wide, like a big mesh. Slowly, over time, we're shrinking the mesh as we understand it better.
I think it's kind of hard to try to measure people carrier to carrier or even to international standards, because we're already constantly improving what we're doing. I think it's difficult for us to actually do that.
