I haven't read all of the entries on this subject, so I don't know if this suggestion has already been made: Yee-Bolson diagrams can test for clone dependence by taking the candidate corresponding to the green region and replacing it with a small triangle of candidates assigned shades of green. If resulting diagram merely replaces the green region with shades of green, then the method passes the test. It has already been noted that if the regions are not convex, then the method fails Monotonicity. So these diagrams can be used to test for these two important properties. Forest
