I guess it all depends on how you view the difficulty of the shots in this video. They are between 1/4 to 3/4 ball shots, and all with english.
The free trial is still open to those who interested to improve their potting skills especially those who view the videos as "Wow, I wish I could aim with english and pot those balls as easily". The only guarantee that Precision Potting can offer is that your potting skills will go up significantly. PP is not guaranteeing that you will pot every single balls, although pretty much every if you have worked on it for a while - like a month.
NDA is to give me confidence that you will keep your promise in keeping the salient points in the system quiet. Other points that are already known elsewhere, of course will not and cannot be covered under the NDA.
I have said earlier that it is not an aiming system. Hence PP is treading on a different path from CTE, 90/90 etc.
Is it a subset of some kind of discussion that has already been discussed?
Laws of physics will apply to all aspects in pool. Precision Potting can't run away from it. So, of course it is a subset of some kind of discussion that had gone through this forum and many other forums. Using a close bridge and pivoting or parallel english is also a subset of some form for any aiming system. Important is, is the end product the same? How significant is the system to each individual?
