From our perspective on Earth, the distribution can appear Gaussian even though the Milky Way’s bulge is really a bar. But, being a barred galaxy, use of a simple Gaussian distribution may not be truly warranted once again, see ref. (74).
The conclusion is that the Postulate is plausible, at least. The only problem is that the Schwarzchild radius, rs, for such SMBHs, assuming a perfect stationary BH, is rather larger than the observed periapse of S‑2. The virtually infinite spin rate of the SMBH below the event horizon could distort it in a way that precludes even an approximate calculation like Schwarzchild’s resulting in rs << Rmin.
