Sorry - I still don't see your evidence. Can you give me a reference/body of work/possible people that I could contact and look at the evidence?
"Why People Believe Weird Things" is a great resource by Michael Shermer. Within the book, Shermer elaborated on many of the fantasy-prone and non-specific ideas that Edgar Cayce had professed.
Beyond their rebuttals - do you have anything else to offer?
