The first reason may actually be a misunderstanding on my part.
I’m running Dragon Reborn Gold and with that program, it’s explicitly stated that there is no endpoint, and the 4 stages can be run cyclically again and again. This is different from Dragon Reborn Red.
There is a major difference between Dragon Reborn RED and the other multi-stage titles you may have used at Subliminal Club. Dragon Reborn Gold has no “maintenance” stage.
So, I may just be taking this logic from Dragon Reborn Gold and going too far in applying it to Dragon Reborn Red. The Dragon Reborn Red copy specifically says you can run stage 4 as a maintenance stage. So, that, as Ksub said, is literally the answer to your question.
But also, I spent the first few years of my Sub Club journey grinding through to “get to Stage 4” with the multi-stagers that I loved. Ecstasy of Gold, The Alchemist, Quantum Limitless. My goal was to, without rushing, get to the point where I could create customs with Stage 4 of my desired programs. I’d typically spend 3 months per stage and then create a custom with Stage 4 and play it for a long time.
I still think that approach was great, and I got much benefit from it. But now I’m in a place where I’m really appreciating stages 1, 2, and 3. And although stage 4 ‘contains the whole program’ for the traditional, sequential multistagers, I still think that there may be some unique benefits associated with revisiting earlier stages. A BLT has lettuce in it. But it’s not the same as eating a head of lettuce. haha.
These points that I’m making may be truer for the newer multi-stage programs. Dragon Reborn Red appears to follow the older way, with each stage building on the other, to some extent.
I’m also running The Ecstasy of Gold right now, and for that one, I’m not even thinking past Stage 1. But again, that’s one of the newer multi-stagers where sequential, cumulative progress is not necessarily the organizing principle.
