Bill Nelson who created the EPFX which was later renamed into QXCI, SCIO and now INDIGO to escape the bad publicity that it had attracted talks about his invented philosophies in which he explains his device. He invented concepts like Sub-space, trivektor and Xroid process with which he tried to coever up the fact that his machine worked with a random-number generator to create its results. In fact the software could run without any device attached as it was basically empty and it was common knowledge that "measurements" were equally possible with out any client being attached to the electrodes
With all the reading ive done about the EPFX, im still unsure if i should cough up the $400 for a session or even possibly buy a used one. Is the doctrine more advanced like mentioned above, basically making this a redundant tool in the arson belt?
