When I'm in go-mode, I'm usually around 200-400 LY above 0. How about you?
Typically? I am all over the place.
My Z co-ordinate is currently -256, but I've been criss-crossing 0 on a nebula visiting trip...
It's Y coordinate, not Z.
I know, but I'd rather have X,Y as the galactic plane and Z as the perpendicular so that's what it is in my head. I may or may not remember to change it when talking to other people for reasons of clarity...
