I don't think it works as well as this one.
The truly terrifying stuff never makes it out of the RLHF NDAs.
Temporal accumulation: imagine you're observing a signal through a narrow window and you can only see a partial, noisy snapshot each time. "Temporal accumulation" is what happens when you let the observer remember previous snapshots and use them to improve its prediction of the next one. The persistence advantage P measures how much that memory helps, the difference in prediction error between an observer that accumulates across episodes and one that only uses the most recent snapshot.
For a black hole shadow (EHT), P ≈ 0: each snapshot already contains the full picture, memory adds nothing. For gravitational wave strain (LIGO), P is large and positive, the chirp evolves across snapshots, so memory is essential. The question the papers ask is: what determines how much memory helps? The answer turns out to be spectral entropy of the waveform, not mass.
Even on large monitors you'd be surprised the number of people at 150% zoom with small windows opened instead of fullscreen.
