Yes. Sure, Noah. So there are several things going on with the Gen 4 design that we're looking at. But if I really boil it down to, I think, the 2 biggest factors, it's a little bit wider inter-well spacing and then obviously, the upsized proppant loading and completion design going to 3,000 pounds per foot more or less. So really, the main cost that you have when you do something like that, you're pumping a little bit more fluid, you're pumping a little bit more sand and you've got a little more pump time. And so ballpark, that adds probably $150 to $175 a foot, something like that. we see in the -- we've got a couple of tests in the ground now where we did this on a pad and had a single well where we kind of tested out the Gen 4 design. We're now moving to the place where we're testing these out where all the wells on a pad are going to be Gen 4 designs to kind of see it. But we think there's a pretty meaningful uplift that is significantly in excess of that incremental cost in terms of overall pad-based IRRs and ultimately, EUR that we would get out of these wells. And so right now, we're excited to kind of see that play out. I noted in my remarks, we've got this spring, our first well that will be -- our first pad, excuse me, that will be a true pad Gen 4 design. It will come online, we expect later in the spring. And so that will be a great opportunity to really see how these wells do. I will note we already rate constrained and rate restrict all of our wells. We kind of hold them flat at around that usually 25 million, 30 million a day. And the other element, though, on Gen 4 and just generally is we're looking at facilities where we would hold them flat at up to 40 million a day. So there's a lot of things playing into that. But holistically, what I'd tell you is we think there's a lot of opportunity here, and we're going to continually evaluate is this a better economic answer, kind of balancing the increased productivity, the EUR versus the costs. On the uppers, it's a similar amount, and we're earlier in that testing. We just have less wells but it will go through kind of a similar process where we test out moving to maybe a larger completion design.
