Comments on the paper by E. Gjerlow and O. Elgaroy "Are all modes created equal ? An analysis of the WMAP 5- and 7-year data without inflationary prejudice"

The amount and characteristics of quantum-mechanically generated relic gravitational waves and primordial density perturbations is a subject of great theoretical and observational importance. Unfortunately, this subject is deeply contaminated by inflationary misunderstandings and incorrect "standard inflationary results". This note presents comments on a particular paper, arXiv:1008.4471v1. However, the comments may have a more general significance and may be of interest to other researchers working in this area of science.
