  We show that a new attempt by C. Corda to once more rehash his so-called
"synchronization effect" in order to account for the origin of the extra energy
shift between emitted and absorbed radiation in Mossbauer rotor experiments (C.
Corda, Int. J. Mod. Phys. D, doi: 10.1142/S0218271819501311) is yet again
erroneous, just as were his previous attempts (Ann. Phys. 355, 360 (2015); Ann.
Phys. 368, 258 (2016); Int. J. Mod. Phys. D 27, 1847016 (2018)). The correct
approach presented herein with regards to the calculation of the energy shift
between emitted and absorbed radiation in a rotating system leads to, as a
matter of fact, no specific "synchronization effect".
