I am putting these values here, which can be used to help guide future objectives in articles 210.8, 210.13, 250, 517, 555 and 680. (And also the foundational ground work to loop and source conduction theory)

Well that sucks, the mesh failed :(

Anyway, further research and theoretical work needs to be done on body impedance while submerged in water and voltage gradients within water- fresh, salt, chlorine, lake, river, ect. This will be able to further give more precise values for automatic disconnection in articles 555 and 680, and also set a maximum impedance for equal potential bonding system design relative to their geometry and size.
