The Spallation Neutron Source is steadily approaching its design beam power of 1.4MW without encountering major beam dynamics issues or unexpectedly high beam losses. This success is a confirmation of a general validity of the models used for the accelerator design and tuning. Nevertheless, it is surprisingly difficult to reconcile many of the measured beam parameters with the model prediction. In this paper we discuss several examples of such discrepancies, ranging from a simple single particle tracking to the beam emittance measurements. We also present our approach on resolving some of the issues from the diagnostics side.
