  Describing the normal state single particle spectral function line shapes of
high temperature superconductors remains an important goal in condensed matter
physics. Recently, we have proposed a phenomenological extremely correlated
Fermi liquid (pECFL) model that promises to accomplish this goal and that is
uniquely distinguished from other models. Here, we present an even more
simplified phenomenological model, which we refer to as the aECFL model, that
performs practically at the same level as the pECFL model. Noting the
similarities of the aECFL model and the pECFL model, as well as the differences
between the two models, we emphasize the universal significance of the
$\omega$-dependence of the so-called caparison factor in the ECFL model.
