Just checked the normalization point. You were partially right, sqrt-normalization makes the difference x2 less. I'm updating the numbers in the post. Interesting moment. I did a smoke test of poly-AE without whitening, and the result didn't change. I won't mention it in the post cause right now I'm not sure if it's a random effect or really a polynomial lift compensates normalization
