Good morning Arun, and thanks for the question. Yes, we appreciate that this is a really outstanding result. It's the culmination of a lot of hard work over the last several years across our teams, across disciplines. But as Dave said, we're not done. And so, that $705 a foot is the average cost performance that we saw in Q1. I think you're probably right to characterize it as leading edge, but one of the things that we've really focused on internally, there's really a relentless drive for continuous improvement. And so, we continue to try to turn that leading-edge performance into our P50 performance. So, one of the things I'd encourage you to look at, not just from a cost perspective, we also disclose our drilling and completion per foot per day metrics to try to give you a sense on a normalized for cost basis what the performance looks like, and so that's really the way that we try to measure ourselves, that's what we control. We don't think just presenting cost numbers, that may have some deflation in them. It is the right way to really hold yourself accountable and measure step change in performance. Certainly, there's a little bit of that in ours, but our objective is to turn all those into structural change and drive those into the plan going forward, which I think is a big part of what you're seeing in terms of the step change in maintenance capital levels and things like that. And so, not just as that Wolfcamp-only performance, really competitive -- exceeding, as you said by a couple of hundred million dollars, other peers in Delaware, if you look at the performance, if you pull in our performance in all zones, not just the Wolfcamp and the Delaware in the first quarter, that number is actually about $600 a foot. So, this isn't a function of just picking a couple of data points and trying to make to make it look good. This is the continued quarter-over-quarter improvement that you are seeing the teams really do a great job at driving. To your question about the facility side, if you fully burden these pads with facilities expense, it probably pushes that average up to about $100 a foot or $100 a foot on top of what we've disclosed there, but even with that, still well south of where we believe our peers are even without facilities in their numbers.
