There is no fresh "it" - it all comes from recognizable sources, and Dan has said that himself in the past.
It's also not from outside the system - unless you artificially limit the system to a particular politically organized structure.
Not sure what politics you are thinking of, here is an example of what I have in mind:
All my direct teachers are students of Saito Morihiro who was a student of the Founder.
The Founder was very particular about the hanmi, Saito Morihiro was particular about the hanmi. My direct teachers are particular about the hanmi.
When Dan says that hanmi makes no sense in his method and that his method is the same one the Founder had, than this comes from outside the system and requires a proof.
