This comment provides a correction to the flawed and non-reproducible study by Sadeghi et al. (2018). By choosing a different but physically consistent set of equivalence transformations than the inconsistent one proposed by Sadeghi et al. (2018), it will be shown how for a temporally evolving plane jet the numerically computed statistical profiles up to second moment can be correctly scaled such as to collapse into a single invariant profile.
