The question is this:
In what way, specifically, do you think Graphite DLC process costs less than the Space Black DLC process?
AFAIK, both DLC processes would cost the same to apply.
You're suggest otherwise.
Please explain your thoughts on what exactly is different between the two DLC processes and why one would be less costly than the other.
The rest of your assertions about cost balancing and so forth are irrelevant without first establishing that the two DLC processes have a different manufacturing cost.
It may be pure speculation as you said, but typically speculation has some underlying support; that's what I'm trying to understand from you.
Sure, DLC is going to cost more than non-DLC. That's not the question.
FWIW, Apple's had the SB and Silver milanese loops at the same price the past two years. $149 from Sept 2018 to Sept 2019, then $99 since then.
