It really depends. There have been projects that have been four weeks and projects that have been seven weeks. Typically the Topic Leader will want to go at their own pace. For this particular project, at a guess I would estimate another 2-3 weeks to finish. Because they are? BST means literally nothing in terms of how strong a Pokemon is. If your question is "why are they strong" then the point of CAP is to test out an idea in a metagame, and as such are designed to make an impact and be, as it were, ecologically successful. The current CAP ended up having a high BST because of all the different things we wanted from it. We wanted a very high capability of taking physical hits, a high capability of sweeping on the physical side, and a high capability of sweep on the special side. Ergo, we ended up with a high BST because that was what was necessary to achieve what people wanted. The low Speed also played a part, as low Speed plus high offensive stats tends to drive up the BST, as far as the BSR is concerned - though this was somewhat mitigated by the high HP.
