Jeff, I think on your question on the, why optimize? First and foremost, I think it's important to say we want to help every customer that is experiencing financial difficulty regain their financial footing if they have the sort of ability and willingness to do so. And at the end of the day, we think that is a great economic answer. It is more importantly a great customer answer. And so if there's ways that we can help someone who, again, has the willingness, has the ability to regain their financial footing, we want to be there. With that said, every single time we help a customer do that, there is some economic cost to that, and that economic cost can be through a rate reduction, it can be through a rate pause. And by the way, that can be sort of impactful to us. By the way, some of the policies also have the potential of elongating a loan which increases the total interest expense to a customer, and that makes it more expensive for them. And so I think this is a case where you really want to be as tailored and you want to be as precise as you can in how you help people, and in a perfect world you would have an individual program tailored made for each person to their individual case and give them the exact level of accommodation that they needed and no more. That's impossible to execute, it's impossible to operate, and by the way, we could never know with that kind of precision what people wanted. So I think, the whole point of a test and learn capability is for us to begin to sort of continue that optimization program, help people with the exact right amount that they need to get back on their feet, but hopefully not help them to a degree that's more than that, which may not be as great for our shareholders or may not be as great for them as individual borrowers. So we will always look to optimize that, but again, I want to really stress, I think the goal is to make sure that we are helping customers get back onto good financial footing if they have the ability and the willingness to do so. In terms of the performance of extended grace versus the other programs, as you can imagine, Pete and I get regular data. I don't think we've seen any material difference in terms of sort of the success rate relative to expectation of those programs. I think we're happy with the absolute performance of both those programs and really don't see any material sort of distance or space between them.
