In the process, we formalise a non-trivial algorithm, namely Rabin's choice coordination. Our correctness reasoning is a combination of termination proofs in terms of probabilistic convergence and standard invariant techniques. Moreover, we describe how qualitative probabilistic reasoning can be maintained during refinement.} }
