  Power counting is applied to relativistic mean-field energy functionals to
estimate contributions to the energy from individual terms. New estimates for
isovector, tensor, and gradient terms in finite nuclei are shown to be
consistent with direct, high-quality fits. The estimates establish a hierarchy
of model parameters and identify how many parameters are well constrained by
bulk nuclear observables. We conclude that four (possibly five) isoscalar,
non-gradient parameters, one gradient parameter, and one isovector parameter
are well determined by the usual bulk nuclear observables.
