Yes, I'd say that it seems that they've followed us which is interesting because of the pricing but, we originally did the increase from that 19.99 price point to 21.99 back October of '17. And that was strictly based on reciprocity which happens to be the most used perk of the Black Card. And we started a decade ago, we had 100 stores. Here we started and we may be changed -- we had probably 1,300, 1,400. So, if you look at today we're -- even today we're about at 30% more basis after we've been tested. So, I think based on reciprocity alone, I think, something we should revisit every year, couple of years, three years whatever, how much and when is a different topic of testing and what the elasticity is just based on that perk alone, but it does beg the question, reciprocity alone could drive some pricing around it. Outside of that, reciprocity piece, we're constantly looking up ways of driving more value for the members. Well, inside this Black Card spa areas, is there a better massage bed that we could put in there or red light or something like that that would drive more usage and more demand. Or, like we mentioned, we talked of the app earlier, is there more functionality with the app where we did some consumer studies where a lot of the members are looking for is, we had to collect their data from the cardio, for example. So by the time they hit the front on their way out, they have their mileage, their pace, their speed, their calories burnt on their app and how it compares to last week or last year. So, could that be a Black card perk that they get, their data? They could be able to look at that and tick their workouts going forward. So, I believe we constantly look at other ways to drive value to the members to make it a Black Card park, which again could drive more acquisition or price or both. So it's definitely something that we're very focused on.
