There is a review of the Genius Code at
http://www.geniusbydesign.com/reviews/secondgen/geniuscode1.shtml that talks a little about the differences.
From the review:
Once again, I enjoyed being led by Win’s voice. And even though I’ve done these procedures many times on my own, I found it useful to be led. And like before, once you have the process ingrained experientially, you will begin to use them on your own...eventually modifying them specifically to meet your needs.
