A variation is when the community limits its growth (such as by being invite-only), and eventually transitions directly from stage 1 to stage 5. In one real-world example of 1->5, I thought that the transition to stage 5 was because growth was limited too much: that stage 5 happens when insufficient new people keep joining. But I haven't seen enough examples to generalize that much.
