Yes, probably, I don't know if this will answer your question. Probably, Frank, the easiest way to think about it is one of the things that we do is we try to analyze. There is a lot of moving parts on the revenue piece, we talked about the lab and us getting that paired off. We wanted it to get it, we talked about some asset we sold, et cetera, but when, kind of, pull it all out, if you just did the most basic assessment, and said look if the margins were flat with last year, what would that translate in G&A. Or if the margins were up versus last year, what would that translate to in G&A investment and you can go right through our G&A and see our COGS are up by an amount greater than that margin. And I can tell you it is a direct driver of our core investments. And then Tom and I have gone to the pieces to say what are those investments, and we've looked at them by division, by area, et cetera. So I think again -- I'll use physician recruitment as a very simple example, but as you're ramping up a recruiting team, as you are buying the data that allows us to be very surgical, no pun intended, in the physicians we want to go after, that are how productivity in the right specialties, as you're doing this and cutting it in every market, you are front-end loaded on that. We already know now that will give us a return that will more than cover our cost in the back half of the year. And then we know, of course, it will ramp up from there, so when we start just bifurcating these pieces out, we could've shown margin improvement versus a year ago, but we really don't think that's the right answer for the long-term. And so our goal is to show you that we're going to keep kind of ratcheting it up a little bit as the year goes back. I think in the next quarterly call, when we talk more about 19 is I think when you'll get a lot more of the optimism we have, because at that point -- we want to see another three months. I mean I think six months in with team is still pretty immature, but we think we get another three months under our belt, some of these initiatives will be able to start showing you real proof points and evidence of that growth.
