We develop, clarify, and test various aspects of cluster dynamical mean field methods using a soluble toy model as a benchmark. We find that the cellular dynamical mean field theory (CDMFT) converges very rapidly and compare its convergence properties with those of the dynamical cluster approximation. We propose and test improved estimators for the lattice self-energy within CDMFT.
