The developers kit lists this method for polylines:
CenterPoint Compute the center point of the polyline as the weighted average of all segments.
Here is a polyline set at the origin (the center is a point placed at the center Osnap):

So why does Rhino show (2, 2.25) for the centre and excel has (2.11, 2.39)?
