"Anonymous.Do you ever practise Backward Walks."
Daily. I also practice related actions that are modified by rise and fall - these are not the walks described in the book, but something different, and more related to actual dancing.
"How can lowering the body possibly affect your timing."
How can it not affect it???
When you are lowering, you are gaining movement energy, in both physical fact and artistic intent. You will have to reflect that in your actions or else look and feel very artificial. Failing to let the rise and fall modify your timing is one of the things that sets beginners apart - they try to isolate each element of their dancing from the others, and look very strained as a result. Wheras on a good dancer, everything is linked.
"The ladies body rise will happen without even thinking about it."
Sure. But it has implications on the foot timing. You may not need to think about those either - but if you are not yet incoprotating that in your dancing, then you will have to think about it until you start doing it right, at which point you will not need to think about it (except when discussing it with those still trying to figure it out).
"Lets think about going to the point of imbalance which you are always on about.If you were to on a Forward Step make sure that the rear toe is actually is a toe and not just a ball, and use it."
Don, when you first go into imbalance your feet are going to be fairly close together - this does not occur at the extreme of the stride as you are describing, but rather near the beginning of the step.
"Split weight. Old book new book. As the RF passes the toe of the LF, the left heel will be released from the floor,so that at the full extent of the stride the ball of the LF and the heel of the RF will be touching the floor. In the actual walk the weight is first on the stationary foot. At the full extent of the stride it is divided for a moment between the heel of the front foot and the ball of the back foot."
What you have just quotes is a description of an EXERCISE. It bears a lot of relations to what happens in DANCING, but it is not dancing - it is a PREPARATORY EXERCISE which is featureless. Dancing modified that exercise with variation in altitude and timing - which together mean body flight, and make split weight innaproriate.
But go ahead and do robotic exercises instead of dancing if that is what makes you happy.
"In a rotation there will still be a neutral point."
Depends what you are rotating from and what you are rotating to. In actual practice, many dance figures will not have a neutral point, but you won't learn about this until you start consulting with better teachers.
"First three of a Natural will do."
A natural turn will see you passing some body parts through rotational neutral in a way that a reverse turn won't. As I've repeatedly pointed out and you have repeatedly ignored, NATURAL AND REVERSE TURNS ARE NOT MIRROR IMAGES OF EACH OTHER.
