I was driving to my Denver office and thinking about the two paths and two speeds idea. As I crossed a train track I started thinking about all the old movies where a car is racing a train and the car either needs to beat the train to that intersection or slow down and let the train pass. The skis moving faster than the body and trying to beat the body into the new turn is one image I came up with. I also came up with the image of the body accelerating to beat the feet into the new turn and the image of both getting there at the same time. In all of these examples there isn't any braking. Not that there couldn't be some braking but for the sake of being consistent with the slow line fast idea I'm not going to include those options right now. My conclusion is that percieved speed relative to each other doesn't mean either the feet or the body are actually moving backwards, it just means one will pass the other as their paths intersect and diverge. Whatever option we choose affects the next turn though and it might make this idea easier to understand if we compare the consequences of all three options. Since this is a tangent to VSP's topic I'll start a new thread, hope to see you everyone there.
Exactly! When they intersect, the balance axis is vertical; at the point of maximum divergence, the balance axis is inclined to its maximum degree for that turn - this progression gives the feeling of the body moving ahead of the feet.
