Mark Fickett Rolls Lots of Dice
One interesting finding that Mark makes for this experiment, regarding number of rolls per die, is: "This leads me to a heuristic of 100 rolls per side (800 for a d8, 2000 for a d20). It is of course a subjective heuristic." This broadly lines up with my own prior recommendation from looking at power curves for chi-square tests on these dice: "For a d6, I wouldn't want to use any less than n = 100 as a minimum (and ideally something like n = 500 if you're serious about it). For a d20, n = 500 would be a useful minimum (and at least several thousand to find reasonably small variations)."
