98% of the people I have known in the past, read the Clark book and did about 50% and believed they did 100% and those that mention the other author I have never heard from that had a clue what they were doing....in both cases, they need to ask those authors what they did wrong and since clark is dead and I have no clue about the other author; their best solution is to start all over.
THIS MEANS, they either take the time to write down every detail of what they did do, so we can see what they did wrong or it is a waste of time for this forum.
