Yeah, sure. First, good evening Robbie and again, thank you for inviting CVRx to present at the JPMorgan conference. That was a great experience for us, we look forward hopefully to be invited in future years and hopefully to meet face-to-face. Listen, the obstacles, if you want to call on this way or the objections that we may face in any new account are very similar to any new therapy. The first and foremost, administration is always wary about the reimbursement and they would like to see a couple of cases reimbursed and paid for. And once they see that, they feel more comfortable. So what we often see happening, centers signing up first for a pilot phase, a few units and then expanding into commercial use, making it more of a routine basis. The second is training of physicians, training of nurses on how to identify the appropriate patients who are eligible to receiving our therapy. And then how to do the implant, which in our case is very simple, the [Indiscernible] is extremely simple. And after the implant, is the follow-up in the management of the patients. What we are seeing though, right now, is possibly a unique situation where we have the confluence of the COVID-19 pandemic killing us sporadically from time-to-time in a geography to geography combined, or maybe causing hospital staffing shortage. And in our experience, what we're seeing, this is possibly impacting us proportionately more than established product lines. The reason for that is the -- any chip, given the choice, and if they have limited time to select few pro -- fewer procedures they can do, given the choice, they will revert back to their area of comfort, their zone of comfort with established procedures. That's why newer procedures end up paying a little of the price here being pushed away, and that's what we're seeing. And why do I notice and how do I notice? We've signed up more accounts than we've activated [Indiscernible] Q4. And when you dig down deep about what is going on, that's exactly what is going on. The staff is facing a shortage of 1 or 2 or having a tight schedule, revert back to existing therapies that they know they're predictable, they know exactly what to expect rather than embarking on a new program. So I don't know, Robbie here, if I answered all of your question in here on what you were trying to get to.
