I wouldn't have much faith in this, precisely because it would have been done based on Newtonian gravity. It does not take care of the MOND phenomenology. With MOND in the picture things may be totally different.
MOND is an empirical equation which predicts the rotation curves based on the visible mass in Galaxies. It works beautifully at Galactic scales but does not work well at cluster scales.
We know that General Relativity (GR) and Quantum Mechanics (QM) both are mutually incompatible, which indicates that something is wrong in both of them. In addition GR does not work well when we get very high gravitational fields like a black hole. The equations lead to a singularity. It works beautifully when gravity is somewhat lower but doesn't seem to work well below a threshold, which leads us to the prediction of Dark Matter, with really weird properties to account for the lack of observation.
Also GR takes into account only one special constant speed of light or the maximum signal speed. It does not take into account the Planck's Length or the minimal wavelength of the signal. This is probably why it does not work well with QM. The modification due to taking into account the Planck's length may cause MOND we don't know.
