One of the sections of MB3D that produces me (probably to some others) the most confusion is the 'Calculation' settings.
The only clear variable to me is the DE Stop: lower it and you get more details.  Increase it and the image begins to fatten in some way.  So, the usual Menger3 you get with DE Stop=1 turns into sort of an irregular ball with this same value increased to 100.
Now, for the remaining 7 values we have the help legends that gives some direction of its impact but no precise indication of when to check or uncheck one of them or the range which is the best compromise between quality and render time, nor the limit that some of them may have.  On the latter, I have read recently that Stepcount for binary search is not very useful over 12 and Smooth normals doesn't need higher than 3.
I include below an acronym of each so to facilitate reference.
DES = DE Stop
VoFOV = Vary DE stop on FOV
RSM = Raystep multiplier
SWL= Stepwidth limiter
SBS = Stepcount for binary search
SN = Smooth normals
NDE = Normals on DE
FSR = First step random

Any idea wil be more than welcome!

Yep, that was me in my previous life  Azn

All i can say is that i begin with high Stepwidth multiplier + limiter and decrease the multiplier until overstepping seems ok, on problem formulas like inverse thingies reducing the limiter also tested.
On bigger pic i test certain parts also with postprocess->Recalc a selection and adjust these so that overstepping is just gone.
All with first step random on to see the random noise.
Normals on DE always turned on to get the normals of the surface, only if this seems to be a problem or for smooth effect turned off.

Thank you DarkBeam for pointing to Jesse who  fortunately is safely reborn and far from the monastery.

O K !! It seems that trial and error will continue to be the method to use.

Thank you David.  This is really impressive.  DarkBeam seems to have privileged information of the real origins of the 'Mandelbrot Set'... or should we call it the 'Udo Set' to be fair?

Anyway, that lead me to listen Carmina Burana.  I always loved it!
