Help me out, what is the "rule of thumb" for NW/$1b?

Looking at you, Xin. :P

troops, jets, turrets, tanks

use the for........ search since this has been asked many times.

I don't remember that stuff. When I need it, I just pluck numbers out from the game and create a new spreadsheet.

You can use $262/NW for non-Demo PM, and $255 for Demo, but more often than not, you won't touch a lot of turrets in the PM and your average $/NW is actually lower. So... spreadsheet it.

Good enough, thanks. :)
