The same study also concludes that a "filter gap footprint" renders it impossible to verify or falsify the presence of a true redshift peak at Δ''z'' = 0.60.<ref>{{cite journal | last1 = Bell| first1 = M.

A 2006 review by Bajan ''et al.'' discovered weak effects of redshift periodization in data from the [[Local Group]] of galaxies and the [[Hercules Supercluster]]. They conclude that "galaxy redshift periodization is an effect which can really exist",
A 2007 [[absorption spectroscopy|absorption spectroscopic]] analysis of quasars by Ryabinkov ''et al.'' observed a pattern of statistically significant alternating peaks and dips in the redshift range Δ''z'' = 0.0 − 3.7, though they noted no statistical correlation between their findings and Karlsson's formula.<ref>{{cite journal | last1 = Ryabinkov| first1 = A.
