Yeah, so, this is Bill, and I'll take that. Certainly, as it relates to marketing, I'd say we saw a benefit in a number of areas during OEP. One, we had fewer agents, in terms of kind of the number of mouse we had to feed, so to speak, that we were delivering. So that gives us and our marketing team more ability, right, to optimize the funnel. We had new data sets and learning, so we were able to take a lot of what we saw during AEP. And as Tim mentioned in the opening remarks, it was a unique AEP, so we were able to layer in and our data science team did a great job layering in these new data sets and really working with our marketing team to optimize what we were buying. And I would say to your question around, when we look at optimizing what we were buying, what does that mean? Are we cutting out channels or not? No, not really. We kind of look at it like that we still want a very wide funnel. Within those channels, there's varying degrees of goodness and amount we might cut within a channel. So there may be one channel that is 90% good. And then ultimately, we can we can let through the funnel and there may be another channel where only 10% is good and we let through the funnel. So, we layered on a lot of those things. And again, our marketing team did a really good job along with data sites with getting those things in place. And I think last just to comment some of the things that we did in regards to retraining, which Tim spoke about earlier, with our agents themselves and making sure that they were really up to speed on the benefits, the benefits of this year's plans also made a significant difference in being able to convert the raw marketing material. As it pertains to the CMS things, we feel like we're very well prepared in terms of already a lot of the things that we do within our scripts. And the marketing changes are really more around the things that you would see in online presentations in terms of the order in which that they present plans, which for us we've always been commission agnostic and are always going to go to the best plan for the consumer. So really no effect there that we see and we're well prepared on that front.
