This is an interesting question. As you may recall, in my case I rotated set_up clockwise until it could go no further, and according to my scope, the waveform still was a little out of spec (but much much closer). That is, it wanted to be rotated even further.
I'll bet this is common to many of the people who are finding full clockwise to work fine.
These were my adjustments:
original = 12:00, final=3:00 (max clockwise)
This change reduced Set_up pulse height from 350V to 285V (target = 280 for my panel).
Original = 3:00, final = 3:30 (very slight turn clockwise)
This change increased Set_down ramp width from 125us to 140us (target = 140 for my panel).
Since then, I went a little further clockwise on set_dn to get a little darker.
