Steering Box adjustment

For those of you suffering with a loose steering sector to worm shaft issue, here is the FSM for the power steering box on my Polara.
It looks like the same is used for all C bodies but you should confirm that first.

What surprises me is that the instructions indicate that all fee play be removed then add 3/8 to 1/2 turn to finish the adjustment...

Has anyone done this in the past?
If so what were the results of this adjustment?
