Experimental Study of 29 Polyhedral Dice Using Rolling Machine, OpenCV Analysis (markfickett.com)

enFi writes: All dice are slightly unfair; automating 3k rolls x 29 dice allows detailed exploration. For example: GameScience claims their d20s are fairest, and actually has the fairest die in the study. Chessex d20s are consistently mid-range and all favor the same numbers; Wiz Dice d20s are highly variable (some rival GameScience). Shape differences measurable with calipers account for some of the larger observed differences, but not everything. Read the details for graphs, a video of the Arduino-powered rolling machine, and an explanation of using OpenCV to sort die rolls.

Nice try, DICE inc, trying to persuade us with your subliminal, liminal and even superliminal messages!

Ah, maybe that's why my games were taking so long. I was rolling 100 D1s.

>> I was rolling 100 D1s.
It might also explain why 99% of your results are between 37 and 63.
Don't worry. That's completely normal.
