What is the typical body resistance in wet locations? Dry locations? I'm at around 200 and 1000 ohms respectively?

Alright, so scratch that. 300 ohms internal or if immersed in water:


The internal body resistance is about 300 Ω, being related to the wet, relatively salty tissues beneath the skin. The skin resistance can be effectively bypassed if there is skin breakdown from high voltage, a cut, a deep abrasion, or immersion in water (Table (Table2).2). The skin acts like an electrical device such as a capacitor in that it allows more current to flow if a voltage is changing rapidly.


Here are the tables from IEC61200-413 as a comparison-
