Question: I have read mentions about a mathematical system to determin the "fairness" of a dice, i.e. does it roll all numbers roughly the same amount.
Unfortunately, I can neither remember where I came across that, nor remember how it was done exactly. It was something like "roll die lots and lots, then calculate how the spread deviates from the norm", or somesuch. Have you (or has anyone else) got a good pointer for me here on how to go about doing that to my dice?

Try searching Chi Square ... I have heard that term used with regard to fairness

It's been a long time since I took a stats course, but I think a good basic statistical test would be a Kolmogorov–Smirnov test to compare a die's results to a uniform random distribution. That's not difficult but it takes some basic familiarity with statistics.

@Kevin Cook do you know any way i can get a good quality well balanced d60 that wont make my wallet bleed as if from a grievous wound? Ive been looking for and wanting to buy one for almost 2 decades and ive only ever found either extremely expensive ones, ones i couldnt verify were balanced well, or could verify were specifically balanced poorly.
