Thanks guys - and again I want to say, that I feel a bit bad and sorry, how offensively I put up the OP.
But it's really that point, which Sageous above formulated - the buildup - the appetizing was on the one hand belittling other methods and on the other promising us the moon.

Why not something like that:
Look - I have thought about all the available stuff and I have changed some aspects of the usual awareness exercises - and now I believe, I've got something special.
It will spare you a lot of time in the long run - but you need to trust me at the outset, because it will go over 20 lectures and exercises and you need to really invest the time to follow them, even while it doesn't seem to be something new nor is it effective after only a week.
But if you do this all - I believe you will ... lalalala

If it would have been in that vein - I would have said all the best for your book - shame it didn't yield the efforts on our side, which would be necessary - but maybe others are more diligent.

But it's as Sageous said it - I was almost directly from the onset in a negative expectation - because of the hyperbole and the slating of other methods, even while over 9 days it was nothing else than stuff from the other methods (ADA variations, mainly).
When I heard that about the 20 chapters - I also thought - ah - something will finally appear, which will justify this.
Well - that question it still open and I agree with the others, who have said, they would like to see the rest.
It goes so far, that I would take the exercises into renewed consideration, if I would stumble on something ringing "significant" by reading through it.

But I came across the fact that you want to mention us in the book - that sort of put me into action for the poll - not that our experiences are going to be sold as a success - I wouldn't like that - and why else mention it?
