I have a question about Controls how aggressive velocity smoothing is. It's a bit counterintuitive, a value of 0.5 means no smoothing, a value of 0.0 means every segment is "smoothed". Decrease this value if the velocity profile seems to be too "bumpy".
ARC_BLEND_SMOOTHING_THRESHOLD = 0.4 I see in the email you had the threshold set to .75?
