Right. So if I take that one, I'll take this the last half first. Yes. I mean, our integration, our sort of vertical integration investment strategy is definitely about driving higher returns on our invested capital base, right? We're taking the intelligence and innovation of all the people in our company and we're focusing on them on how to make things, how to get the barrel of oil up to the surface at a lower cost at a higher profitability for Liberty, right? So that's key. That's key in everything we do. So that is that focus, that really makes a difference, right? Yes, does the ability to run the CNG business. Yes, one of the things we saw was that we were not running maximum substitution because of the ineffectiveness of a CNG and natural gas supply system. That was a key limited, right? And as you move to 100% natural gas engines, that become major limited because gone is the additional cost of running excess diesel from a dual fuel equipment, you've got downtime if you don't have debt, right? So that was key for the initial part of the investment in LPI, right? I was really making sure that we drive that efficiency. I mean, I think that's a key thing there on how we are sort of managing to keep up in a softer market when we've got about a 20% decline in activity demand over a 2-year period, Liberty is basically flat and has the strong returns, the continued strong returns we have is because we deliver more value every day to our clients. And I think everything we do is focused around managing that and improving that. Now as Chris says, as things tighten up as they will. I mean, eventually, diesel it's a cyclical market, right? We're in a lowest point at the moment. Things will tighten up. You will see the sort of forcing function effect of all that investment in vertical integration will also, you should see that improve the bottom line faster as we go forward as the market tightens, right? These are long-term investments. So I think that's key there, Derek. And I may have missed the first part of Scott's question there but I got on a roll, so.
