After 250 rolls, 1 popped up 27 times. Or roughly 11% of the time.

I did this same test with all 17 D20’s I have and 2 D20’s from people in my DnD group.

This one was far and away the worst though I had more than I’d like with averages under 10.

Edit:

Here's the stats for the ones I tested

This excludes the data for the 2 D20’s from the people in my DnD group as they didn’t want that data shared outside of the group chat.

    250 rolls is really low for a d20 test, not enough to spread out the randomness over all surfaces. 1000 is also on the low side, but has more chance to indicate a bias.
