 Factor
-   The portion of the total length of the spline at each control point.
+   When the node is used on the point domain, the value is the portion of the spline's
+   total length at each control point. On the spline domain it is the portion of the
+   curve's total length at the start of the spline.
 
+Length
+   When the node is used on the point domain, the value is the distance along the spline to each
+   control point. On the spline domain it is the length along the entire curve at the start
