I think there's a deeper issue to identify here: this model means that you and your team are 2 or less weeks from "failure" AT ALL TIMES. There's a psychic cost associated with that that doesn't really facilitate creative work.
It's crazy that the term "sprint" stuck as a way to describe a development cycle. The last thing I want to do after a sprint is another sprint.
in running, what do you do after you sprint? you rest, not sprint again. yet in this tortured metaphor we keep sprinting and then sprinting again and again. where's the cool down walk, where's the stretch and refuel, where's the hydration?
