Practice makes perfect (I guess).
I can do this "I like to bring the indicator in from above - centered vertically (by eye) on the Z axis. Set it on a flat side. Gently rotate the chuck back and forth a bit - the indicator reading will bottom out and start going up again - take note of what number it bottomed out at.
Now carefully pull the plunger of the indicator up to clear the stock (1" stroke indicator is best here).
Rotate the stock 180 and carefully let the plunger back onto the stock. You don't want to be moving any handles or pulling the indicator stand around will doing this.
Move chuck back and forth to get "low" reading again.
Now adjust the chuck to be half way between the 2 readings.
Keep repeating all around the part over and over.

I am less than 5 min per cycle on 4" stock in a 36" chuck.
I spent a lot of time on a 4 jaw many years ago.
