I agree on not focusing on a rigid elbow and/or shoulder.
I'd agree if someone said, "Who cares if you drop the elbow, are the balls sinking?"
I'd add to focus on things like the tip going down to near or on the cloth following the stroke if you're using a pendulum, rather than worrying about the elbow drop. An elbow drop is fine if it happens not too early...
Piston or pendulum, if you're making the shots...
