I very much think so. Disjoint groups turned out to be a > 10 week issue and not a few short weeks issue. (we hoped 2-3 weeks plus plenty of time to test) The plan is to push ahead as soon as we can. In another way though i thought the core guys time to get a lot of work done in data handling. So a silver lining, but disjoint groups took us by surprise at it’s complexity. We are on it very hard though and will crack it.
