Thanks Todd. Yes, one of the beautiful things about this model that is very different than the systems that have been in the past is our supply chain is – our vertically integrated – sorry, our vertically integrated supply chain is very – is a huge asset for us. And our strategy that makes sure that the innovation doesn't negatively impact the supply chain allows us to be very flexible, on the timing and the cadence of our promotions. So, I think we've talked about it a couple of times that we projected to have between, call it four and five new, big promotions and LTOs over on a yearly basis. However, we believe that if we have a big winner, someone like Stuffed Crust, then we are able to continue to sell that ongoing and continue to drive disproportionate sales, for our restaurants. And doing so there's a lot of flexibility, like in the past a lot of QSR chain, you have this calendar and you have ingredients that you need to bring in and take out and its kind of drives, okay, we have to execute as a way we built it. For this model, we're even have a lot of flexibility, a lot of optionality. And so, if we've got something that's really resonating with customers, we can extend that. If we have something that maybe isn't as big of an idea, we can shorten the amount of time that we focus our promotions on those items. So, with Stuffed Crust, it's been a huge success, we're going to continue to promote this, probably a little longer than maybe we would have promoted something that wasn't quite as successful. So, in terms of the amount of support that we're putting up against it relative to last year in Q2, and Q3, the level of sales, obviously, this model in our national marketing fund is an outcome of the sales in the system. And as our sales grow so to our marketing dollars. One of the things I was really concerned about early last year, looking all the way ahead to 2021 was how we were going to be able to laugh the We Win Together investments that we made in the marketing funds. Well, not only are we laughing those investments, we're feeding those investments as an outcome of the increased sales across the system. Year-on-year we are increasing the amount of investment behind our promoted items relative to even what we did back in 2020. So, lots of fuel to drive these grades. ideas and lots of flexibility on how we promote them and the cadence of our innovation.
