22:21 Yeah, I'll give you a couple of thoughts and then let Andrew dive in here, Nick. But I think the – the incentive comp in Q4 was higher a because we performed better, but there's also a component of a catch up, right? So we're running an accrual all year, based on sort of budgeted performance. And then over time, as we start to realize that we're performing in excess of budget, then we start to bump up the accrual. So I think the short answer is you can't just back it all out and assume that it's the normal run rate. But Andrew compared Q4 to Q3, which is probably closer to a normal run rate if we hit budget. So, we've made some changes to make our variable comp, a little more variable, if that makes sense. So I think the good news is we're a little more aligned in terms of making sure that pay for performance is there, but it makes it a little harder to predict the run rate, because you don't necessarily know you're going to hit budget a little below a little above. 23:25 So I think, it's Q3 is probably a decent proxy for a run rate, but even that's not a perfect number. And on your second point, we're certainly keeping a close eye on expenses and wage inflation. Obviously, there's a lot of information out in the press about what's happening, both in terms of the ability to retain folks and what you need to do to attract folks. So I think we're trying hard to make sure we can keep a lid on that expense growth as best we can. But I certainly expect that kind of the base rate, salary levels next year will be higher. Traditionally, I think we were looking at 2% to 3%, kind of inflation-based increase, and I suspect that number will be – will be higher by a 1 or 2 this year. But we've got other ways to manage that right? And you have got what you pay per person and then you've got how many people you have and how you reallocate work to make sure you can stay lean and so we're looking at all those factors and short answers. I think expenses will be up almost certainly, but I think we'll do a good job, trying to manage that growth. Anything, you would add there, Andrew?
