I personally believe that the Final Immunity Challenge of Cook Islands, "Self-Destruction", is a different challenge from "Perch."

With regards to the "I Hold On" challenge, I think that if "Perch"/"Self-Destruction" are considered to be two different challenges because of a simple variation, then the different variations of "I Hold On" should be separated because the variation was much greater.

They should be split into:
 * "Hanging By a Thread" (Fiji)
 * "Splash Back" (Nicaragua, Blood vs. Water)
 * "I Hold On" (One World, Caramoan)
