Bob, I agree entirely as to fault levels. Just about every basic electrical text will have some sort of chart (or table) of fault levels. Most of these don't reach 'certainly fatal' until well over 50mA. Values under 10mA are described as various levels of shock.
If nothing else, it's safe to say that the 5mA level wasn't pulled out of thin air.
NOW - and I think this is what you're getting at ... a person CAN die from a much smaller shock, if the conditions are right. The level of shock felt will even vary by individual.
You will note that I did elaborate, and discourage the idea if using a higher setting.
