The major problem with that is we are incredibly good at gaming the system. I've seen mediocre, at best, team became a glowing beacon under the velocity game; they managed to close 2000+ stories in one year! (a developer closed well over 1 story per day on average).

Software estimation is a really hard problem. We can attempt to establish order by pretending that burning down/velocity charts actually say something useful. How do they work when all the methods we know fail? No idea. But have faith, because we have plenty of anecdotes of its success!
