@JeremyDow3 @Mandlbaur @demystifysci The guy has his own subreddit (r/Mandlbaur). He's been having this same conversation over and over for a long time...
He submitted his stuff to many journals and the results were as you'd expect.

I get your point—the ideal calculation gives ~12000 rpm for typical ball-on-string params (e.g., r_initial=1m, r_final=0.1m, ω_initial=120 rpm, assuming rigid pivot, no drag). But real measurements are lower due to pivot elasticity, wobble, and friction, as modeled in peer-reviewed work. This doesn't falsify conservation; it highlights non-ideal conditions. Share your exact params for a Python sim?
