Query: On what scale should inflationary observables be constrained?   We examine the choice of scale at which constraints on inflationary
observables are presented. We describe an implementation of the hierarchy of
inflationary consistency equations which ensures that they remain enforced on
different scales, and then seek to optimize the scale for presentation of
constraints on marginalized inflationary parameters from WMAP3 data. For models
with spectral index running, we find a strong variation of the constraints
through the range of observational scales available, and optimize by finding
the scale which decorrelates constraints on the spectral index n_S and the
running. This scale is k=0.017 Mpc^{-1}, and gives a reduction by a factor of
more than four in the allowed parameter area in the n_S-r plane (r being the
tensor-to-scalar ratio) relative to k=0.002 Mpc^{-1}. These optimized
constraints are similar to those obtained in the no-running case. We also
extend the analysis to a larger compilation of data, finding essentially the
same conclusions.
