That makes sense. I’d be curious what that software is like, sounds really interesting. An earlier iteration of Guesstimate involved a directed graph; it seemed promising, though in this case I changed it for common usability.
I believe programs like Crystal Ball have ways of indicating correlations. This seem difficult to do both technically and in the UI. I’m trying to make Guesstimate for a much more general audience than Crystal Ball, so it’s more important to make things really intuitive.
