…Did you say that it takes only 45 minutes from pushing code to it going into production? Typically yes. So that battery of tests that I described, that gets run on every change, that gets run in parallel to when you send it for review by another human. So it's run once, typically takes about 15 minutes and then once the changes merged into our code base, we run that same test suite one more time. So another 15 minutes then typically takes about 30 minutes for the systems to automatically deployed in production. That's how we run and think about establishing that tight feedback loop with users, that means you can get feedback from a user in the morning, you can figure out how to address it and you can actually put something back in their hands by the end of the day. And that loop running inside of 24 hours I think is pretty important. That's incredible.
