Just look at the actual data:
I’m currently up to 7500 tiles seen-that’s over 200 raids I’ve recorded–and the stacked into color is still essentially exactly 1/5 of all tiles.
The reason you see people asking for proof of your claim that the boards aren’t random is that we have really good evidence that it’s wrong.
And if you think random systems don’t exhibit good runs and bad runs, you don’t know what random really looks like. If there were always 7 of each tile on the board, it would be the exact opposite of random.
