>>57970473He doesn’t explain it well, it goes more like this:
1. Biboo plans a collab.
2. Biboo streams just before the collab for her stream to then become a waiting room for the collab itself. This boosts her viewers on the earlier stream.
3. Biboo then self-raids the collab with the waiting room that is waiting for that collab. This lowers potential viewers for the other Holos who agree to collab with her.
4. Biboo has also extended her stream length, to not just start as a waiting room, but also stream long enough to receive raids near the end too. Basically, taking advantage of both positions, with both giving a nice bonus.
Whether you think this is right or not, is up to you. I already shared my thoughts on it before.
