That is pretty amazing. I actually didn't know that, but let me ask you some questions about that. So you said you started with 200,000, you got it down to several thousand, and then you chose 450 based on demographics and then they were in 45 rooms of 10. And so there would be, because that itself kind of reflects Dunbar's number of sorts that you have to bring it down to a manageable human interaction level and then scale a little upwards. So did each room of 10 come up with its own kind of verdict?
