FCTM T/O or climb section explains the 70/30 acceleration logic. I can't recall reading it for descent but from operational experience you will tend to see RoD around 700fpm. In THR IDLE you would also be in DES or OPN DES where pitch controls speed. You can read about that as it relates to speed control by searching "open descent" in your manuals.
