* A team that is being judged on scrum velocity can simply keep inflating story points to make it look like they're going faster.
* A team that is optimistic has a lower velocity. A team that is pessimistic has a higher velocity.
* If a story is 8 points that gives no clue as to whether it ought to be a 2 point (if the technical debt accrued by the team were not so high).
In practice I've found that it doesn't stabilize either. Of course that automatically means you just "weren't doing Scrum properly".
