How strong is the orbital clustering evidence for Planet Nine?

I've been trying to wrap my head around the latest data on the hypothesized Planet Nine, and I keep hitting a wall with the orbital clustering argument. I think I understand how they're identifying these patterns in distant Kuiper Belt objects, but the sheer scale of the proposed orbit and the indirect nature of the evidence makes it feel like such a long shot to pin down.

I spent a few evenings reading the clustering papers. The Planet Nine idea is big and seductive, but the orbit is enormous and the evidence feels indirect. It sort of sits on the edge of being convincing and being a long shot. After staring at the plots, I keep thinking maybe the sample size is doing more work than the physics is.

I did a quick back-of-envelope test on my own. Took the cataloged distant objects, shuffled the sky biases, and checked how often they line up by chance. The result swung a lot with tiny changes in what you assume about detection limits. It left me unsure what to trust.

The report hinges on a few specific clustering angles, and the math behind it feels fragile when you look at it from the bench chair at home. It’s easy to talk about a signal, but the noise from undiscovered objects could swallow it. I try to stay skeptical.

Maybe the problem isn't the hidden planet at all. It could be that the belt's distribution is shaped by earlier moves of the giant planets or by something we haven't modeled well. I keep wondering if we're solving the wrong puzzle while the data quietly drifts.
