Thanks for the epicycles clarification, I did not know each body had its own fitted set. This makes the parallel with overfitting even stronger.

And I think we agree on the real problem: a good fit on one problem, made with a universal approximator, is not an explanation. It can be just a compressed description, maybe with a cause behind, maybe not. I cannot fix this, but I added this week a small thing to at least see it: a bootstrap stability check. You resample the data, refit, and look how often the same form comes back. High frequency does not prove anything causal. But low frequency is a good signal that you are only looking at a Fourier-type fit, not a law. The decision stays with the user, the tool only makes it visible.

Too late, but I hope you see it. In the original post you said:

> That's Kepler's Third Law (T² ∝ a³), which took Kepler ~10 years to find in 1618. GP_ELITE found it in ~3 seconds.

In future post in HN I recommend to avoid that kind of comparisons, because we all know he did that on paper and didn't even have a good set of functions to use a brute force aproach. It feels like unnecessary linkbait and make people write unfriendly comments. Probably it's better:

Thanks for the advice; you're absolutely right ,it was just to grab attention.
