Thanks Scott. So, our definition of what enters the pipeline hasn't changed. We have leadd from patients and their families through the social media, Facebook, Google activity plus to get referrals from doctors and therapists and rehab hospitals and own t clinics. So, when we have a customer experience team that does this over the phone, they interview the patient candidates. We ask for their insurance and we verify that they would have likely reimbursement from some of the plans that are regularly reimbursing for the MyoPro and then we get their permission to collect their medical documents. So, we have to get a doctor's written order we get their medical histories. For example, they had a stroke seven years ago, they're chronically paralyzed, they want to go back to work and use their arm again, medical necessity. And then, our reimbursement team prepares the package to submit to the insurance company and that either goes through an O&P provider or 90-plus percent of these new pipeline patients are through our direct billing channel. So, when we submit those directly to the payers that points out, they're considered part of the pipeline. And the number I'm very pleased with, how large it has expanded here to over 300 in a quarter. we're doing 100 of these evaluations and the big change. You may recall a year-ago, or plus, we used to set-up screening days around the country, We get patient leads and then referring to, for example, we're going to do a screen day in Chicago or New York or LA, which might be put out might be a month or two later. So, we've compressed that timeline and we're doing it by telehealth. So, our field clinical team is able to have someone if they contacted us today, our customer screen team will verify their insurance and we can set up an evaluation tomorrow. And it takes maybe an hour, hour and a half video conference evaluation. So we have really compressed that time, but also it's an ad saving significant amount of travel dollars. So, that's why moving from these in person evaluations and doing all by telehealth has enabled us to increase that pipeline significantly even from quarter-to-quarter.
