Yes, but then it wouldn't be replicating a real world situation of the cutting forces involved during normal turning.
Damn you
@thestelster ! Another excellent point! The question is "Which approach is better?"
I will have to give this some thought and perhaps some research.
It also begs the age old question of how much is too much.
I always like to establish what my gut says before I dive in too deeply. Failing to do it right away, despite the risks, robs one of the opportunity to do it all.
At first blush, I think it's better to start as close to zero as possible and then factor in the various real world effects. Since the real world varies so much based on a plethora of factors (speed, feed, depth of cut, material, etc etc) factoring them in too early then requires a double change to factor them out and then factor the new ones in. Better to establish a zero and only factor in once. Aligning a headstock is not something we want to do whenever something changes.
But perhaps it's something that should be evaluated and quantified before worrying about it.
Lastly, how much fussing is warranted? Perfection for its own sake is more-or-less a waste of time. Does it really matter?
I don't mind thinking about it and even doing a few tests to evaluate it, but after all that is done, I still need to be convinced that it matters. If not, I prefer to move on to things that do. In this regard, my views are biased.
