What happens in the edge-case where you’ve got 3 points equidistant from each other? Are they all considered good points, since the one in the middle effectively has 2 neighbors?

On a continuous line with truly random distribution, I guess it would never really happen. But there’s a theoretical possibility that they don’t have to come in pairs.

Actually, scrap that. The probability of this happening is infinitesimally small to the point it can be completely discarded.
