Of course its arbitrary, but you gotta pick something. We optimise for progression. Failing a sprint doesn't actually have any real ramifications. What we use failure for is a signal to indicate problems. Missed? I guess we have some talking to do in retro to figure out what was misunderstood. Missed three sprints in a row? Is there a problem we need to resolve? Similar to misses, we don't really get much from shipping on that cadence either, other than progress and building confidence in upper management to base their timelines on us delivering what we expect.
