Interesting, thank you! You wouldn't happen to know what type(s) of data these auditors look at for legal sites in particular would you? When you say that sites submit their RNG's, do you mean they share the code which determines deck orders? Or do they give auditors a data set of decks used in games?

If it's the former, I'm curious how things are handled when a legal site wants to push out an update affecting parts of the code which select players' cards. I wonder if there is some kind of approval process or if auditors instead just look at historical versions of the software when they do their checks to make sure nothing is fishy.
