Okay. I think I understand now.
You also asked... "...there might be something documented in an IPC standard
somewhere that addresses ways to calculate job complexity, etc."
Yes, there is a reference to 'density evaluation' in the IPC-2221 spec - par.
3.6.2 (pages 12 - 15). (It was pretty much copied from the IPC-D-275 spec.)
I hope this helps.
