Re: YouTube: Push Test to Nikkyo
One more thing about the 150% rule . . . if the demonstrator doesn't effectively explain/train the observer to do the same thing, the observer will be left to try replicating the demo via known avenues thereby possibly replicating a demo but not the actual substance of the demo, or worse still (from the viewpoint of replication/transference), attributing the demonstrator's ability to something "mystical" since what is outside one's realm of knowledge often appears to be accomplished via magical power of one sort or another.
Of course there is the whole fallacious demo thing but that is a subject unto itself.
