Excellent..
And you do point out when you might want short, large conductors: for 
minimization of hum / line frequency interference, because that's a 
"resistance is dominant" application.

I do wonder,though, whether "circuit diagram" is a bigger effect in most 
situations than "resistance of bonding jumper".  The resistance of the 
75 feet of #14 or #12 greenwire ground to the receptacle on the other 
side of the room is going to dominate the 3 feet of AWG whatever 
connecting the rig to the next box.


I love the idea of ganging multiple (metal) boxes together to provide a 
single power feed point.
