How perfect is roundness in a neutron star?

That a neutron star has a fractal like surface is extremely unlikely, due to the extreme gravitational potentials that exist. The surface gravity may be approaching [math]10^{11} g[/math]. It's high enough that general relativistic corrections matter in fact, making the gravity even stronger. The gravitational redshift at the
