As far as most Controls guys being Masters equivalent, I would disagree, however I don't know many, I just know one. He did have a masters, and he wasn't nearly as good as he thinks he is. and a lot of maintenance / electricians do get into controls in Plants, that is because it is easy to know a little about controls, however actually studying controls and understanding is a very different thing.
