QTR-Quadtone RIP

In anybody's experience does a greater number of grey
step samples (ie 52 or 100) help during the Profile
creation step of QTR.
For curve creation using more than 21 steps has always
been no good for me, 21 works best. I also profile
with 21 steps, but was wondering if anyone had better
results using more steps. Just curious.
Right On
