A thought for me is to almost feel like my hands a dropping through the ball with their own weight and I am not helping it. Try practicing it with 5 and 6 irons. This helps greatly with distance control if you are controlling how far the ball goes based on the length of the stroke.
Had a 9i with me today so I did some green-side chipping with this and the idea of same tempo back as forward. Much mo betta.
