We describe our theoretical behavioral modeling research in specific domains where finite-state models really can be found. There, with precise model-based design and perfect model checking, we obtain correct results by constructive inference, adequate testing and verification. In actual software development we find these results can only approximately apply. Still we show they can assist in software design that is "less incorrect", consistent with the results of theoreticians and practitioners working in actual model-based design and model checking.
