Yes, I think the, the one thing around this Ben, is that, in the first quarter, I mean our earnings were good and it's been and marketing cost as a percentage in net revenue were higher than they typically would be through the course of an average year. And we attributed that to seasonality, which was a part of it, but invested in that also was a component of these costs being too high. So it gets, it got masked a little bit, I would say, from expecting the cost to be seasonally a little bit higher than they would be through the rest of the year. And then as we got into Q2, typically, what you see in Q2 for our business is that as middle marketing cost actually comes down pretty significantly within our guidance range, and so that on a year-to-date basis, we are comfortably in our range. And that did not happen this year. And so, as you sort of look at the way the numbers roll through the year, they were too high in Q1, we are expecting to bring them down. It didn't happen fast enough. And so you have this bulge in the second quarter. And that's really kind of the way that it has shown up. I think historically, they have been high as well, but from a utilization perspective, again, there were certain puts and takes in our admin and marketing costs, which wasn't less apparent. And so, I think that's, that's the explanation. And it does, it's called out pretty prominently. I mean, if you look at, our toll has been the marketing costs. The piece that we've pulled out around excess labor is bigger than sort of aggregate variance than has been the labor, because we had other expenses that roll into that total. It came a little bit more favorably. So there's always been kind of offsetting these amounts, which make it more or less apparent. And so, I, that is as best as we can explain it Ben.
