It's completely based on demand. So they say from the accounts, it was a little over $7,000, which equates to four kits, which if they use every place, I would say they don't, because they have to do some repeats in humans, but that's about 160. We're making the revenue from 160, if that makes sense. And actually you probably noticed in the script, it was two and then I said three because they just reordered a few days ago and there's some time between recordings. So when they run out, they order more basically. So that's going I mean, this is about the revenue, of course, but it's about the learning from the beta launch as well. But it's very nice to have all these things been sorted out with, we thought the best way to really learn all these things is to actually have real paying customers, there's dozens of bits of auditors, Texas A&M have given us great feedback, it's on the actual running of the test themselves. And as I said, the actual test is working absolutely perfectly. This is all the marketing and the packaging, and all those kind of things. But yes, so the audit 7000, which is about 160 times and then we audit, it was three times last week, and that was three times. And they just keep reordering about let say, I guess really adjusting I'm ordering as they finished up the previous one. So that's exactly in line with where we thought they'd be. We haven't obviously done a lot of marketing where we've done a bits and pieces with the key opinion leaders and throughout Texas, but obviously nothing nationally. So this is the kind of the level we're expecting. And it's been absolutely great from the feedback point-of-view. And I think it's really helped us up enough headroom for the international and national launch. And also, again, I think it's really focused the mind on the big companies that the trains moving, if they want to get aboard, they've got to get aboard. I think if we'd not launched, I think there will be lots of wasn't a level of interest before we launched as there is now. Because at the moment we are the monopoly in the space, there is absolutely nothing else out there in the cancer space in the NETs market. So I think we're in an excellent position. But if we can work out a deal with one of the majors, I think that's would be very good pressing good for them. But if for any reason we don't, then we find the ability we can watch ourselves. So I think it's been an absolute win-win all around.
