In a review of "The Premonition Code" by Theresa Cheung and Julia Mossbridge, Debra Lynne Katz complains that the authors' "Positive Precog Training Programme" is really a "rebranding" of an abridged version of Prudence Calabrese's Trans-Dimensional System, which itself was adapted from Ingo Swann's Controlled Remote Viewing technique.
