Interesting plotting there D. But can it be laid over the Golden Spiral graph? Im not sure if they are apples to apples. Not sure how they measure or designate their center. Maybe. But your point is a good one regardless. From many zones, one hand path.

Im also wondering about plane shifts. Take the Golden Spiral and look at it from a down the line view say. Would the spiral be seen to travel a flatter plane angles as it gets closer to impact? Like a funnel cloud or water going down a drain. So the hand path would be approaching the center (what ever that is) and flattening out at the same time to a degree consistent with the plane angle or shift. Elbow plane for some types. Moe wouldnt have much of a shift though. The more the shift the more conical the spiral.

PS dont think that is Jason Zubak. But who ever it is he is LONG. Why do you say the TSP will steepen the hand path? Do you assume axis tilt?
