I think the author got the right answer, but checking their work, I'm not sure they got it the right way. Sprints are actually really simple. You know how you work on something for a year, and then Google I/O is coming up where you're going to show it off to 3 billion people, and it's not done, so you just say "ya know what, I don't even CARE about these features we said we'd have" and you launch whatever you happen to have checked in on launch day? That's sprints! Except with sprints you do this every two weeks instead of every year.
