Calzone, thanks for challenging my beliefs and forcing me to devote the last two days to study and testing. It became obvious that the resaerch papers were very contradictory and the fact that they left out essential testing details made it impossible to figure out what was what. So I went to the open market here in Ecuador and brought back some cow meat and blood. My testing of the two showed that for the exact same volume blood is more conductive than meat but since meat is so volumous then it is definitely is an alternative current path. My studying informed me that bloods conductivity was from the blood serum (liquid), which is rich in electrolytes, and not the blood cells which are non-conductive below 100kHz. Bloody beef was much more conductive than bled pork so that was the clue that the conductivity of meat is mostly from the blood. So it has to be that electricity leaving the electrodes of a Beck Electrifier goes both into the arteries and into the blood-rich muscles. But all the blood of the muscles connect to capillaries which connect to veins which connect to arteries. So although the electric current is spread out in the forearms (with electrodes on both wrists) by the time it reaches the shoulder it is mostly inside one of the two main arteries. (One carries oxygenated blood and the other carries de-oxygentaed blood.) These arteries cross to the other side thru the trunk of the body where very few veins connect to them. It is there that the current density is all important.
In a 16mm cross-area artery the current has to be 124uA to equal the 100uA/13.3mmsq of the Lymann/Kaali test, and it has to be 62uA to equal the 50uA/13.3mmsq of the test. But the current is divided between the two arteries and so needs to be twice that, between 124uA and 248uA. So my customers that set their current to 130uA have been getting effectivess equal to Kaali/Lymanns 50uA. So now I am going to reset the trigger point in my electrifiers circuit to 190uA to equal the midpoint between the researchers 50-100uA/13.3mmsq. If people want to make the current higher than that then of course they can just by turning the control knob CW.
Becks error in testing electrical current flow in the artery is that he tested an artery in the arm whereas the only place it should be tested is the almost impossible location between the shoulders if the electrodes were placed on both wrists. That is where the current density is sufficient to affect microbes in a maximal way. In the arm the current is divided between the arteries and the muscles. If Beck did this test while having both electrodes on one wrist then he committed a double error. Most of the current was just crossing the wrist to reach the other electrode. That is probably why his recommendation was to use the intolerable amount of 3mA. Despite his two errors he actually was right in saying you have to use 3mA if you want sufficient current in your arteries when using the electrodes on one wrist.
