I found https://arxiv.org/pdf/2201.10385.pdf by the same authors.

If I read it correctly, it says the theoretical limit for thermal evaporation is 1.45 kg/(m²h), while experimentally, values as high as 4-5 kg/(m²h) and over 10 kg/(m²h) have been reported in two-, respectively three-dimensional structures.

That’s a huge difference, but in my uneducated opinion not likely to be completely caused by this effect.

Edit: reading https://news.mit.edu/2023/surprising-finding-light-makes-wat..., which says “and the excess has been significant — a doubling, or even a tripling or more, of the theoretical maximum rate”, I read that correctly. I’m beginning to doubt my “not likely to be completely caused by this effect” hunch, though,

First pdf source says it happens in darkness with hydrogels too, but doesn't directly say the magnitude (has another reference), just that it is smaller.
