Joanne Wuensch: Good evening and thank you for taking the question. I appreciate the sequential commentary. I just want to make sure that the first quarter gets set up. I mean, how are you thinking about the sequential quarter in terms of revenue delivery, and I will ask a follow-up question. If I did my math correctly, you ended 2022 with roughly 300 physicians trained. Are you in a position to establish a goal for 2023?
Erica Rogers: Well, why don’t we take those in reverse order, Joanne and thanks so much for joining us and for your question. So, in the year of 2022, we achieved roughly greater than 400 physicians trained, which was in excess of how we had guided in the first part of the year, ending the year with roughly 2,500 physicians trained, which is a great setup for 2023. As we have talked about before, training physicians is kind of an investment in our future. And you probably noticed, Joanne, that we did not guide to a specific number of trained physicians for this year and 2023 and we probably won’t go on forward. And that is because it is, it is kind of de minimis compared to the number of physicians that are already trained and the real growth driver being moving these train physicians up the adoption curve.
So the best way to think about it is kind of mid to high-single-digit percentage growth and train physicians every year from here on forward. And that would include, of course, fellows, and younger physicians coming in replacing the old retiree.
Lucas Buchanan: And, Joanne, your question on sequential growth was Q1 of this year versus Q4 of last year, is that correct?
Joanne Wuensch: Yes.
Lucas Buchanan: Yes. So I will reiterate some of the prepared comments and if there is a follow up, let me know. But again, the historical trend has been roughly flat, but the historical trend includes some COVID spikes in various time periods. We ended the year with 70 territories and started the year with 70. And again, have a goal to expand. And so I think a lot of sequential growth is the right way to think about Q1. And then as we as we get the year progressing and continue commercial expansion and continue all of our initiatives and continue the on-slate rollout. We will have some sequential step ups from there with the normal seasonality adjustments that we make. But at the end of the day, it is really procedures per doc and what are the inputs around driving, driving physician utilization and obviously, having the folks out in the field, go do to their thing more and more with more touch points is the goal.
Joanne Wuensch: Sounds good. Thanks you for the incremental answer.
Operator: Thank you. Our next question comes from (Ph) of Stifel. John you are open.
Unidentified Analyst: Hi Lucas, hi Erica thanks for taking my questions today. I guess to start off, taking a look at operating leverage for 2023. Maybe putting a finer point on it. In 2022. You grew top line around 37% and OpEx is around 2024 like a 13% delta. What do you see in 2023, do you see that GAAP potentially widening, as you kind of reach more scale with the Salesforce or do you see OpEx kind of continuing to grow in that mid-20s percentage range?
