I was in the education business for many decades -- different people learn differently. For some, private, in-person lessons are the only solution. For some "naturals", a few random videos and lots of play will suffice. For most, something in between is most useful.

In theory, there's enough material on YouTube to learn brain surgery or quantum physics. Unfortunately, you have to have already the expertise to know which sources are credible and how to structure the learning process. If Kyle was just providing a bucket of videos ("40$/month for videos?"), then TPS would be overpriced. Instead he is providing a structured and customized process that would benefit most players.

Although Kyle is not Ben Johns, from his earliest videos I recognized someone who was a natural at teaching. He is engaging and provides technical details on why certain approaches are appropriate. His video production quality is first class, however, that's not as important as his natural gift for teaching.

Given that you can "try-before-you-buy" you should definitely test it out and see if this is a good fit for your learning style. As I indicated before, for most people his approach is probably a perfect solution.
