Well, it's a good question, Ron. The ultimate benefit is well performance. And we're clearly seeing, in lot of the examples I just went through in my remarks, significant improvements above the type curves, our average type curves, that we've got published. So, to me, that's always the true measure is are we seeing it in well performance. And we are. It involves a lot of things from well design, from the standpoint of what target it should be in. Although the Marcellus is one compact package of shale, if you want to think about it that way, there are different layers in it. And, again, we talk about the super-rich, the wet and the dry area. But what this machine learning capability allows us to do is take this tremendous amount of data, whether it's geological, geophysical, rock properties, all of the completion histories and reservoir pressures and everything else that we see there, and look at this in multi-dimensional views. In other words, there's no bounds on the machine as to how many different things it can consider at one time. And so it allows us to take an approach to use all of those things you mentioned, whether it's changing the perforation design, cluster spacing, the proppant loading, the amount of fluid that we pump, exactly which target we put the lateral in. And it allows you to look at not just one well on a specific well basis, but it allows you to take your capital program and say what's the best way to get the best return in well performance out of this amount of capital in this field with these sorts of parameters. And so it's been a really eye-opening experience for an old frac guy like me to see this team and the technical ability that they have today to develop that. We hope to do the same thing in North Louisiana eventually, but it will take some time. Again, we've only had that property for less than a year now. And we're beginning to apply a lot of those technologies, but it's going to take a long time to build that model.
Ronald E. Mills - Johnson Rice & Co. LLC: And then just to clarify, did you say the recent six wells that you mentioned in Terryville, are those the first wells that you've done from soup to nuts in terms of Range drilling, design completion, design (38:36), bring online? And would there be any legacy Memorial wells left, or have you moved through that whole inventory?
