Dan, I appreciate the question. This is Jake. So we've done a lot of work around that. And it's certainly something we've spoken quite a bit about in the last couple of quarters, particularly on the heels of 2021, where we spent about $65 million in CapEx and a lot of that geared towards productivity improvements, driving efficiency, taking some pressure off the labor force and so on and so forth. When I look at that margin, the 300 basis points, you break it into a couple of buckets, and we think a lot about durability there. I'd start by saying, as you appreciate, about 80% to 85% of our COGS is what I would call a true variable cost, whether it's material or labor ex some of the stuff that's going to be a little more fixed inside those categories. And when we saw this productivity it really hit the margin line, both in gross and operating margin it is coming more to the labor side just by the nature of how we experience that in our income statement. But before we even get into that 300 basis points or 400 basis points of lift on our operating margin, I'd tell you, we still had about 100 basis points of headwind from freight in, some material cost that was lagging getting through. So while we're pretty active on pricing as we've spoken about in the past, some of that still is dampening down some of the results that we saw. But as you transition through that and think through the components, I'd tell you that of that 300 basis points we think there's some absorption certainly across the remaining 15% of COGS that is relatively fixed and we've seen that pretty consistently over the past couple of quarters of strong production. When I think about the labor side, there's probably call it, 200 basis points in there that -- of that about 100 or so basis points is related to productivity improvements. So it dovetails into what Jeff had said, where we can do more with less, where we've seen both stabilization in our labor force, we've seen tremendous wholesale shipments. As you noted, as well as a little bit of restocking at the OEM side. We've been able to really leverage our -- these improvements, whether it's some of the automation we've done, the software we put in place, the planning for longer runs and everything else, leads me back around to probably -- we're planning on 100 basis points of that being good durable lift in our margins on a go-forward basis.
