That's a very good question, Jack. And we gave data on that in the past month saying 1 to 1.5 test a day is an accurate math, clearly, when you only refer to 1 assay which is respiratory or in this case, COVID. The way I see it for a syndromic system, you need to take into account seasonability -- seasons in a year. When you have, for example, a high flu season during the winter time, I think having or expecting an average of 2 to 2.5 test a day per module is something which is perfectly reasonable. In a normal situation, 1 to 1.5 is a good number to factor in. For the coming utilization, it will all depend on our menu progression and we have always been clear on that. This is why we always said that QIAstat like NeuMoDx, by the way, is a menu play, it's not a COVID play. So we have two good things this year. First of all, for the first time, we are in the real position to answer any kind of tender in Europe which was not completely the case before. Why? Because the minimal expected menu to be competitive in a tender on a syndromic is at least respiratory, GI and meningitis. We have it now in Europe. So we were already competitive without meningitis. We will become more competitive with meningitis. Second, in the U.S., basically, at the moment, we have two assays. We have the respiratory normal and the respiratory plus, i.e., with COVID. Adding GI and now we are expecting the FDA obviously to approve the test, will help and we want also to submit meningitis to the FDA in the U.S. before the end of 2022. So if we continue to increase that menu, moving to an average of two tests on average is something that we can keep in mind, yes, per day, yes. It depends also on the specialization on the hospital or the site you are in your QIAstat, Jack. Some will never do anything else than respiratory. Some we -- will combine the menu. So that's why, by the way, adding also the Rise to our portfolio on QIAstat is extremely important because it will help us go into greater laboratory hospitals of 400 beds plus and those normally are using multi-targets with the syndromic, not just one assay. So you're correct. Your math is correct at the moment. With more menu, I would try to factor much more 2 to 2.5 test a day.
