well... you find it hard to believe yet it's real, it's even the fundamentals of microconductors, why do farms use immersion?
Would you like to try what I said before denying it?

I tinker in the firmware, so I know how they work, and they are optimized to have a constant efficiency in particular, do you think that their low power update is magic? no .... just an adjustment, I found that on most of the 19 series, they work very well with 200W less, even hashrate, just downvolt a little ...
The palm d'or returns to T19, 84th for arround 3150w of origin... after optimization works at 95th with 3100w... (in real, is S19 renamed on T19 with poor parameter)
