How to determine nozzle is done

I made the mistake of download temperature towers from the print area, g code version because I was too lazy to encode the temperatures in slicer. 
Unfortunately for me, and a warning to you, those g code files has some modifications for the z axis before print. 
 
what this did was it embedmy nozzle into my print bed, drawing very nice etched lines. This was a nozzle-x

how do we know that the nozzle is done?  Do we measure it with calipers? It does not look as pointy at the tip as it once did, and I noticed my zxis has shifter (probably because the nozzle itself was crushed upon itself). 

have you pushed your nozzle into the bed before by accident ?  Do you replace your nozzle after such an occurrence ?

Last question: will replacing the film On any destroyed sheet give me a flat surface again - or will the film contour back to the divots.

Just out of curiosity (and I'm certainly not going to try it) will stock Marlin allow gcode to move the Z height negative?

I only replace a nozzle if the prints are starting to have poor quality because the extrusion is getting wide from the bore increasing.
