Let me take a first crack at that, and I'll let Dennis some of numbers there. So, you know, I think as Dennis mentioned, we've had now two nice consecutive percentage growth quarter-on-quarter. If you remember, we're about a year into the initial - the first Lucid test center launched in September of last year, so we're not even barely a full year in. And as an essential, we hired literally our first sales rep, calling them primary care physicians in the third quarter of last year. So now we are as of belief today, we're at 20 and we're moving towards 40 for the end of the year. So I think the simple answer to your question, Anthony was that the steady growth quarter-on-quarter we've seen for the last few quarters is directly attributable to allocation of resources to building a sales channel -- sales, a group of sales reps, expanding the number of test centers and the support to allow the sales reps to generate referrals to the centers. And it's directly a reflection of that. It's also reflection of something I'd love to talk about a little bit more depth on the Lucid call, which is that we have -- our sales leadership has done a really great job of honing the sales process, which you think about just kind of walking in and talking to a doctor and getting them to do the test. But it's actually quite a sophisticated process here with how we target, how we route, how we -- all the top tracks around that, and it's quite to this data to organize data driven. And that process has definitely helped sales training has gotten much more intense. We just finished one couple weeks ago, it's you know, it's a in-depth, really intense field training, field right, along with an entire week of classroom training. So that's been helpful. So I think our productivity and the time from a rep starting to them being productive in terms of generating test volume, think will portray. And, you know, I think, that really is the -- those are really the key factors and we obviously are expecting to continue to grow. That's why we're investing in this team. We like -- we think, kind of 60 for the end of the year as a good number to kind of pause that and then allow the, you know, the sort of run with those horses for a bit to grow within those territories and within those reps in place. So yes, I think hopefully, that's all kind of a long winded, yes. I don't know, Dennis, if you wanted to elaborate any further on that.
