 \section{Gentle Inflection at End of a Bend}
 
+The example in this section was clear, but insufficient: it does not specify
+how many vertices should be included when calculating the end-of-bend
+inflection. We chose the iterative approach -- as long as the angle is "right"
+and the distance is decreasing, the algorithm should keep going; practically
+not having an upper bound on the number of iterations.
