I think specifics are necessary, because general statements can be interpreted to mean anything the reader wants. What you're written covers everything from basic "relax and move from the center" to actual high level skill. In the beginning, every track is close to every other, so being on the right track itself isn't that meaningful. It's going a long way down the right track that counts, and that requires specifics.
That makes a lot of sense. Trouble is I've mostly been thinking in theoretical terms and discussing it from that point of view. Hence a lot of people saying they want specific exercises and so on.
Doh, wish I'd replied to this post before writing the other really long one.
