I haven't, no, sorry. Doing these tests has pretty much eaten up most of my stamina for die-rolling statistics... Even this post was mostly made out of frustration at being told I was making it up...
I'd generally expect simpler systems to use simpler, free to acquire RNGS, while systems for whom that d20 roll is the backbone of their game to fork out for more advanced ones that aren't free.
I should probably request that this all be branched off into its own thread, however, since this thread is meant to be for the synopsis of the stream, and for discussion of the stream, and potentially the contents of the upcoming patch... not another debate about RNGs and dice...
Thanks for taking the time to do this. I'm actually still skeptical, but I do appreciate the effort involved here.
Note that my skepticism is based on personal experience... as a graduate student ~25 years ago I noticed a similar pattern in some simulations that I was running for my thesis, and I had an absolute panic attack over them. My advisor said "run more simulations" and as more were added the weird sine pattern went away.
In any case, you might be on to something. I intend later to do some additional analysis on your data if I can find the time. I may also try to collect some more rng data to supplement this set.
