Yes. So, I mean, I haven't had any overt inputs that are -- I'm -- give me pause or trepidation or concern about long delays, Tycho. I think the reality is that, again, what CMS is hoping to do is to try and get this implemented as rapidly as they can. You know that we're in a public comment period right now. As you might imagine, in typical fashion, all the constituents that have a stake in the outcome here, being led by ASTRO are assembling information and putting their information together to be able to present to CMS. I think, when you think about what they've communicated so far, what CMS has communicated so far, there are -- the big topics, at least from what ASTRO was saying and what I'm gathering is that, the national payment rate, the view generally is that -- the census is, that it's low. There are also a whole series of withholds and adjustments that will be a part of the payment model that are going to need to be worked through. And so, I think, that there's going to be some negotiation and some movement on those before the music stops playing and something gets definitively rolled out. But I know that CMS wants to get moving on this rapidly. So, I think, that that in general should try and create an environment where it moves this along. I mean, I think that there will be some people that will probably take a wait-and-see approach to, if they are in the midst right now of purchasing decisions definitively. But I think directionally, people that are understanding what CMS wants to have happen here with regards to the movement to SBRT case mix and hypofractionated treatment delivery, I think that, if you use that directional context for what the world is going to look like and how you're going to have to be operating it clinically, I think, it takes a lot of the confusion out of, or the potential confusion out of where this should land. And, again, it supports a more rapid -- people being able to make decisions about what they need to do from an equipment standpoint.
