My thinking was to use as close to radial spokes as possible to keep the ramp approximately level in section. Perforce that results in smaller segments on inside curves and larger segments on outside curves. [/quote]
it might be right and i’m just seeing weird right now 
a test might be to draw a curve which starts with a very small radius then smooths to the point where the last couple of vertices are very far apart… seems like then it would have noticeably shallower angles in the nearly straight sections.
