These guys, probably just a guy with phenomenal sense of humor, are running to win the prize of some sort. And they/he may make some money along the way.

All grounding schemes from component to earth have different levels of impedance (ground potential). We know this much.
By no means am I an expert, but by wiring each component’s chassis (earth ground) to the grounding box and adjusting the settings, the theory is that an equal impedance to ground can be achieved.
