There is no valid reason to have a WSB for Steel Challenge. OK, MAYBE for Showdown and Outer Limits with the boxes. But if you are at a L2 or higher match the competitors should already know this. It's 5 plates, shoot them in any order you choose, shoot the one with the red stick last, repeat 4 more times (3 if OL).
It's Steel Challenge, not rocket science. There are no poppers, no "best x hits on paper", no ports, no leaning around walls, no activators, no mandatory reloads, no need to walk through the stage, etc.
When I saw that in the rule book I just shook my head and more-or-less ignored it. It should be removed in subsequent publications.
