As for your question, it's 95% of what it used to be. That's essentially how the promotion system worked 6 or 7 years ago.

Here's the deal. Joe makes E5 if his PSG and PL send him to the board. If he's not ready, don't send him. So many senior NCOs and officers who complain about how quick Joe makes rank forget they're the one's sending him to the promotion board. If you don't think he's ready, dont put him in front of the CSM in his Class As.
