  We present a re-analysis of the cosmic confusion hypothesis, elucidating the
degree to which ``confusion'' can be expected to hold in a class of flat,
adiabatic models. This allows us to devise a simple and accurate fitting
function for the height of the first peak in the radiation power spectrum in a
wide range of inflationary inspired models. The range preferred by current data
is given, together with a discussion of the impact of measurements of the peak
height on constraining models of structure formation.
