Hey, Whit, this is Brett. Yes, to answer your first question. So, normal cancellation rate for us is around 15%, 15% plus. So, to see a cancellation rate at 20% that's a pretty significant increase. And as you know, the cancellation rates during COVID have been anywhere from 16% to 20%. So, actually 20% plus when you go back to 2020. So, you see that that level was pretty significant for us. Fortunately, it came down sequentially month-over-month. As it relates to your question, I think you're, kind of getting to where are we seeing volumes headed, kind of going into the future and also what impacted volumes in Q3. So, if you think about Q3 2021 on a same store basis, we saw volume increase of 6.8%. So, it was a pretty difficult comp. In addition, as Saum alluded to, we did feel the lingering effects of COVID on staffing and physician availability and the cancellation rates that you referred to as well as obviously the impact on our ASC’s from Hurricane Ian. And just from Hurricane Ian, we saw probably anywhere from 2,300 to 2,500 cases that were lost in September. Fortunately, we've rescheduled a large majority of those cases in Q4. Also getting to your point around physicians, I think in our conversations with physicians, the story for their offices is similar to ours as it relates to practice volumes being right around pre-COVID levels and the expectation or the exception I would say to that as ortho and GI specialties that are slightly outpacing 2019 volume levels, but I would say most are optimistic. Most of the physicians are optimistic that once we get past the trailing impacts of COVID, then we'll see more of a recovery in their offices, which will obviously translate into surgical volume over time. All said, we do believe that we'll get back to normal growth rates as the physician offices recover. And as we continue to build out to your point, our professional sales force, which we have been doing in that special sales force continue to collaborate with our operators to develop and execute very center specific sales plans. And of course, as we implement new higher acuity service lines across portfolio. As Saum mentioned, that's a significant part of our growth story as it relates to improving not only our acuity, but also our volume trends. So, we've implemented 70 new service lines so far, 70 plus new service lines so far this year and we have another 150 in the pipeline that we'll implement in Q4 and in 2023.
