If the course is working for you, I would not question too much about whether paraliminals or fast finish for example are effective. Paul and Jack use a good variety of tools and techniques. Some will benefit one individual more than another. Some may be more beneficial at a particular time more than another. Also it may be difficult to quantify or see what benefit a particular tool is having. Some of the visualisations and meditations do appear to have some instant results but I believe that sometimes paraliminals are changing thoughts attitudes and behaviours more subtly over time.
I am just trusting that following the tools and techniques are going to bring about the desired the results
