\Kepler\ planets around a given star have similar sizes to each other andregular orbital spacing, like "peas in a pod." Several studies have testedwhether detection bias could produce this apparent pattern by resampling planetradii at random and applying a sensitivity function analogous to that of theKepler spacecraft. However, \citet{Zhu2019} argues that this pattern is notastrophysical but an artifact of Kepler's discovery efficiency at the detectionthreshold. To support this claim, their new analysis samples the transitsignal-to-noise ratio (SNR) to derive a synthetic population of bootstrappedplanet radii. Here, we examine the procedure of sampling transit SNR anddemonstrate it is not applicable. Sampling transit SNR does not set up random,independent planet radii, and so it is unsuitable for corroborating (orfalsifying) detection bias as the origin of apparent patterns in planet radius.By sampling the planet radii directly and using a simple model for Kepler'ssensitivity, we rule out detection bias as the source of the peas-in-a-podpattern with $>10$-$\sigma$ confidence.
