You aren't hearin me, bro. I don't want to be shown anything the public isn't allowed to see. The book has been published. I don't want to know what the real form is like, I'm only concerned with what has been published by both parties involved. You aren't doing anything that jake couldn't do on his own because it is all public material.
Markers are small changes in order to put a signature on a form and also used to hide secrets. Agreed? Ok what I want is a marker from the book and then show me where jake is doing the marked movement. I will have to take your word for it that it is indeed a marker because you don't wanna show secrets and that's fine.
So I am not asking you to show me differences, I'm asking for similarities. You understand?
So when you see a marker in Jakes form you know that even if it was a very common form, you can show that the form was copied from the book because only those who got it from the book would have those markers.
Unless your argument goes like this: "nobody knows the form therefor you got it from us" and that is your proof that is thin. But if you can identify copied markers you can prove it is from that book. Otherwise you can't for sure pin point where he learned it. Feelin me?
