  Holographic models of superconductors successfully reproduce certain
experimental features of high-temperature superconductors, such as a large
gap-to-T_c ratio compared to that of conventional superconductors. By
deconstructing the extra dimension of these holographic models, similar
phenomenology is described by a class of models defined in the natural
dimension of the superconducting system. We analyze the sensitivity of certain
observables in holographic and deconstructed holographic superconductors to
details of the extra-dimensional spacetime. Our results support the notion that
certain quantitative successes of simple models of this type are accidental.
However, we also find a certain universal relationship between superconducting
observables.
