OK, here's what I think I know:
The newer individualized surfacing abilities for SV or progressives have power ranges available (such as "up to 4 cylinder, etc.).
There's no "physical" reason that you cannot order outside this range.
The limitation is in the software that has been written to date, but it will expand as time goes on.
How mangled is my understanding of that?
Second issue:
I hear company "Z" has less limitation than company "S" because it "designs on the fly".
What's up with all this?
