Yeah, so let me start Doug by addressing that. So, with regards to Q1, yes, as you mentioned, we grow 14% in terms of sequencing consumables. As we look at Q2, as I mentioned in my prepared remarks, our expectation for sequencing as a whole is to grow in the, essentially the low double digits or approximately 12%. If you also exclude some of the one-time factors that we had in Q2 related to some tariff stocking, that sequencing consumable growth in the second quarter is improved by roughly three percentage points. In sequencing as a whole, we expect that business to grow by about 15% in the second quarter. Now, as you think about the ramp in the second half, obviously, as we've talked about in the prepared remarks, there's a significant ramp in the second half. You would say, I mean, traditionally, we've probably been in more the 48% to 52% in the second half, building in terms of revenues. Right now, we're saying it's more 46% to 54%. But if you factor in the ramp from some of the population genomics initiative, it probably normalizes closer to 47% to 53%. With regards to some of the things that are going to drive that backend loading or some of the improvements in sequencing consumables in the second half, obviously, the ramp in terms of instrument placements is back end loaded as well and that's going to carry with it consumable utilization. And we are seeing very strong consumable utilization across our instruments. I mentioned the NovaSeq pull through number, which was $1 million in 2018. We expect that to improve as we go forward. So that's our expectation, and we see no reason to not expect that. And then the other metric that I mentioned, actually, another couple of metrics that I mentioned, one was around our, I would say, our largest customers and those are experiencing a 40% growth in terms of sequencing consumables across their clinical application. So that's a significant growth, we're seeing very, very strong utilization in those group of customers. And then the last one is around some of the metrics that we mentioned overall around clinical utilization and growth in sequencing consumables across clinical. For 2018, that was a growth of 30%. For Q1, that was actually a growth of over 20%. And we expect that for the full year to grow in line with what we saw in 2018. And again, we're seeing some very strong indications with the applications that we see that are growing in clinical. So we feel really bullish about the second half. Obviously, it's a steep path, as we talked about, but we have very good indications for the achievability of it.
