Point of information:
The Power and Power Plus processes were developed by John McMaster, an assistant to Hubbard during the 1960's. McMaster also developed R6EW, routine 6 end words. Hubbard stuck his name on the issues and tried to take credit for them.
McMaster suffered the same fate as everyone else who attempted to help Hubbad, he was persecuted and gotten rid of. He also happened to be gay, which Hubbad used against him after McMaster was gone.
