Let me start by first just talking about what we have seen in Q4. You would have seen that, Q4, our sales ramped from Q3 to Q4 by about 15%. And this is typical in a QA/QC driven business. It's muted versus historical trends, which are roughly 24% for Waters. But in a QA/QC driven business, you do see a ramp in replacement towards the end of the year. That trend is very much intact, especially outside of China. I think it's naive to think that replacement cycles have suddenly stopped. This Q4 ramp tells us that replacement cycles are still ongoing. Now the underlying question is, what are driving these replacement cycles and how do you trigger them? In a muted CapEx environment, the conversations we've had with customers on replacements have largely centered around new products, Arc HPLC and Alliance iS, which have both gained a lot of nice receptivity. So, new products allow you to continue to have that conversation. And you see that reflected in our sort of pharma results outside of China and as you compare it to our peer group. Now, to your question on did we see an outsize replacement during the post COVID years? It's very difficult to tell. We think it was more a push back from the depression that you saw during COVID and outsized execution that we saw due to the replacement cycle that we had not had from 2018 to 2020. So pent up demand sort of helped us get really outsized growth. Now, to corroborate that point, if you just look at LC, LC is 70% replacement business. And if you look at how we ended the full year 2023, so LC – and again, one should look at long term trends, on a long term basis, is roughly 1% growth on a four-year CAGR. So LC is growing roughly 1% on a four year CAGR basis, which is well below the long term average of about 4% to 5%. And you add pricing, so it's actually 4-ish-percent sort of below in volume versus the long term trend of 4% to 5% LC growth. So we do expect LC replacement to start imminently. Now don't ask me exactly when that inflection point is. Short term, we have a ton of visibility with a lot of data and a lot of conversations with customers. Long term, we think the trends are going to revert back to the mean or even better, given what we've talked about in our prepared remarks. The inflection point you don't get any extra marks to call it. So in 2024, we've assumed the same trends as 2023 to persist. But, definitely, we believe LC is due to come up in growth rates. So, long answer, but I hope that gives you a lot of context on how we're thinking about it.
