Yeah, I think the important part of Q2 is really that timing element, right, we were a little bit late in Q1. So we had some favorability there, you know, some of those costs rolled into Q2, and now you've seen some, you know, higher costs as it relates to Q2. Now, at the end of the day, a lot of those costs for us, we expect to even out. So yes, in a perfect world, we would have those perfectly spread out throughout the year, but there is an element of timing that just coincides to, you know, the tactics and the development and where we're deploying those dollars. So, I think the largest thing I'll highlight there is, you know, Q2 did have that element of timing, we would expect, you know, again, the components of that line are largely the 2% that's contributed into the national marketing fund. And we always try, you know, to spend that full - full pool of funds each year. And then the second is our local spend for our clinics. Now, we've got more clinics coming online, each of those, we have a grand opening marketing cost associated to it. And so with that, you know, we want to make sure they start on the right foot. And so you're going to see some additional sales and marketing that come through from those grand opening efforts as well. So, you know, Q2 kind of has a little bit excess in it, as you know, we were a little bit late in Q1, that's that timing element. And then you've got the other factors to consider as we kind of move throughout the rest of the year.
