I don't think anyone ever explicitly decided that this analysis should have one set, but you're also just kinda wrong here? The only times when Vic was relevant and actually very good in RBY OU since I started playing, it was achieving that by running sleep+wrap+razorleaf+filler. SD+HB has been kinda irrelevant for a good while now. I definitely don't think only mentioning SD+HB in OO should cause anyone to be "incredibly appalled", I can count the times I've seen that work in a high level match on the fingers of one hand, and I strongly disagree with the notion that Bel is defined by its unpredictability, because one of the sets has been incredibly popular and the other is only a fringe option.
But, I would leave these sort of arguments for when we agree on what the fuck's going on with this analysis, and who's gonna host it going forward, because there's some confusion there for the time being. The mon itself has even shifted downwards in usage and viability a crapton since the analysis was first written, which means there's a lot of work to be done to bring everything back to an accurate state I think
