Not a particular one, mostly gathering info from an ungovernable misfits video from 2023 time. Talks about how you need way more rolls than some people think, iirc it's like at least 50+ for 12 word and 100+ for 24 word. Might have that backwards. Don't quote me.
And when you flip coins, you are creating the bits yourself 0 or 1 so you really are random. People quote flaws in dice, they recommend getting casino dice, seems for the 'provably' random part. If I find any de facto culmination I'll be sure to post, but right now mostly a hodgepodge of various forum posts and videos from throughout the years.
The last thing we want is someone rolling a seed with 15 dice rolls thinking they are good ya know.
