hawkrider explained it pretty well, clubs doing official steel challenge will be using the stages you find in the steel challenge rule book (what my club does) other clubs doing speed steel will be doing random stages that the organizers come up with and will generally change each match
steel challenge stages are set up the same distances every time so you can take your score and compare it to anyone in the world that also shoots steel challenge.
the abby fish and game steel challenge is every tuesday night practice and matches once a month, here is the video from our last match
