Hi David, thank you for your interest.
The various stages of learning, such as the “Powerplant Model” you mentioned, are a framework to create a conceptual understanding and roadmap; these tools help internal arts practitioners check they’re learning and progressing efficiently. So as a practitioner is training Yan Shou Gong, they can refer back to the roadmap outlined by Master Yap to see how far they’ve progressed.
As Master Yap mentioned during his explanation of the “Learning Triangle,” the path to proficiency in the Nei Gong arts is built from three parts: Theory, Practice, and Technique. This course provides the theory; however, it will then be up to the student to practice and develop the technique through Master Yap’s guidance. For example, skills such as Rooting, Song, and using Jin result from persistently training the Yan Shou Gong sets; they are not causes.
Master Yap and his students actively respond to any questions posted in the group. We are also in the process of filming a Q&A session and additional videos to help the students progress. So if you do enroll and have any questions relating to the lessons, you can always find help and answers from Master Yap in the inner-door students’ group.
I hope my response is helpful and offers you some insight.
Best regards, Kieren.
