Tested with an rda shorted with copper wire (speaker cable as I don't have anything else) and got 0.019. Set the mod resistance to 0.016 and the Bellus is working fine. The Serpent still doesn't want to cooperate though.I left mine at .003 and it's working fine in TC using Ni200. Yours does seem a bit high. Here's a link where they are talking this very subject.
