 Can we talk a little bit about the challenge itself? So it's kind of interesting. These aren't specific problems. These are almost find a problem and then tell us how you can solve it sort of deal rather than other challenges where it's specific scenarios and things like that. How do you judge it based on those kinds of the problems that they're solving? Do those factor into the actual judgment itself? And what kind of timeline do you look at? How long does it take to figure out who has the best tool?
