IMO, shoulder means: power from legs, core, and etc.
This power produces just 15% of the racket velocity.
The arm and its parts create 85%.
Thus, the arm actions are much much much more important than legs, core, and etc actions!!!
I think what rKelley is saying, which I concur with, is that Bruce Elliot's data does not withstand the scrutiny of practical experience to the contrary. "The proof of the pudding is in the eating," as they say.
