So I'll take that one, John, if you don't mind. So thanks very much for the question. First thing I'll tell you is that when you look at the quarters turn rates, when you, we don't publish this information for you guys, but when we look at the, the aggregate, the components for that, the monthly pieces, the January turn rates were very, very strong, very high. And as we saw the COVID-19 hospitalizations begin to drop off, and they dropped off very quickly after they peaked in the first or second week of January, we saw that drop off pretty rapidly from, from well below what we've seen for historical norms. We started talking, obviously out in the field, talking about all the customers and what they were telling us is "There's no flu anywhere in the system at that point in time", and we haven't seen any flu in north America in any, any capacity whatsoever this year, nor have we seen any kind of RSB. But what it did do is it let our field team get back into the accounts. You know, by the time we got into February, our people were back on the ground back to teaching, training, coaching. So we're hearing stories like what I shared with you guys on this call, we're hearing more and more of those stories. Like now, I'm able to get back into these accounts and I've been able to see it firsthand. I'm telling you, I think this year's going to be sloppy, but I'm very excited about what I see for the end of the year, in terms of reverting back to our historical norms. And in fact, because of the number of gold accounts that we've been opening, you guys know that those gold ED accounts turn at a higher rate than non-ED accounts. So what we're, what we're working on doing is to make sure that we're educating the heck out of everybody on using this technology on hypercapnic patients now. And we, we can see that what we're going to get to by the end of the year, and feeling very good we'll be back to historical norms.
