What percent of channelers are channeling a hidden part of their own mind as opposed to an outside entity?

The percent channeling an aspect of their own mind is a relatively low number, at most, 20% at any one time. And this includes many who attempt channeling as raw beginners, and this may be the first thing that happens, and is never actually witnessed by anyone, nor presented publicly as a true authentic channeling. It is a learning stage, a beginning stage, that usually is perceived as faulty or inadequate, and representing a failure to reach the desired level, so is not a great impediment or hazard, but simply a pitfall for the unwary to avoid.
