Or does a 4.0 really need to slice the ball in order to control and limit it's depth?

Yes he should.
Why does his rating even have to mentioned? He's asking about that specific shot and tips on performing it.
OP, a more extreme racket drop would work, as well as a slower RHS and taking the ball at the right height to give you the required trajectory.
Check that your grip is a correct eastern BH grip, turn your shoulders and set your feet properly, bending your knees. Just because you are warming up short does not mean you shouldn't use a full and proper stroke, albeit at a reduced pace and intensity.
