Do you think there's any correlation between focal ratio and the generations of these artifacts? - Steeper light cone = better/worse rings??

Yes, I think the longer the focal length (which could be a steeper light cone) the worse the rings get. If I use a 5x powermate it can be quite severe. Although the detail is pretty nice overall. It can be overcome by doing a flat, but that is even more trouble.
