I asked the same question recently and was told that the program is not what it claims to be. I liked the way it looked and it seemed to make more sense than speaker workshop and some of the others I had looked at but I was steered away from it by people that I feel were being honest with me. I can do a little research to get a better explanation but I believe that the jist of the comments was that the results you get are not based on good science.
