Thanks @Saberem. To confirm, your results are all from Patch 4, right?

Visually, your data doesn't show the obvious sine-wave pattern that @Niara's data did, but this could be due to randomness, the smaller sample size, or perhaps Larian did some secret fix to their rng between patches 3 and 4. Although, your unweighted rolls 30-75 do show a suspicious lack of results <5, which could be part of a sine-wave pattern with a period of ~50+, and thus not visible with only 100 data points.

I agree @fallenj. @Adiktus, any chance you could update the title to "Suspicious rolls" or "BG3 die rng" or something like that?
