Yeah, I don't know the averages. But as you know, it actually depends kind of, you can almost think of it which county you're in. So, if you're in kind of the heart of Midland and northern Upton, today it's easily five zones at work and it could be as many as eight, because you've actually seen, and if we roll up and include Martin, which captures the real core of the basin, you've actually seen everything from the Jo Mill to the Middle Spraberry all the way down through the Wolfcamp C working. And in fact, one of the interesting things is that we were pulling some of our Midland Basin assessment work from 2014 and looking at what was working then and what we thought might work, and the list is a whole lot bigger today than it was then, which by the way, we believed would ultimately happen. But things like the Jo Mill and the Middle Spraberry were kind of gleams in the geologists' eye at that point as opposed to real. So it's expanding. As you go to the east and start to come up out of the basin, you sort of move into the more of the two to three zones, which will work. In terms of spacing, there's two dimensions to think of there. Laterally, I think what we've shown is we've gone down in the high 300s all the way to 660s. We think it will vary a little bit by zone and county. Generally, it will be less than 660s. We don't think it will be 330s, though. It's maybe 450, 500, but it will vary some. And then, some of the zones, particularly the Lower Spraberry and the Wolfcamp A are so thick, they may take two wells in sort of a wine rack pattern to ultimately recover the resource. All that's still evolving. But I would say when you're in the core of Midland and Upton, what we're doing now is kind of focusing on up to five zones. And then if you think that you could end up with something more than eight wells per section, that's how you get into that 40 to 50 wells per section. And then, if you go over into maybe somewhere like Howard, where it's three or two to three, you may end up more like 25 to 30.
