I've added the rare success, but made it a link to a non-existing article so that we'd know that content should be added with proper explanation and figures (like the Broad Difficulty page).

btw, i think the proper way to calculate rare success rate is #rare/(#rare+#success) (in case of the stairs its ~8.5%, but i put it as 10% for now) because both regular and rare are successes.
