      Ah, damn, I hadn’t accounted for polydactylia. Wikipedia tells me 4 to 12 people in 10.000 have an extra finger, which is more than I’d have guessed and it gets in the way of my 7.3 in 10.000 estimate. It’s counterintuitive, too, because I feel like I know more people with nine fingers than 11 or up.

      It gets complicated, because it can also happen with toes, which we’re not counting, and some amount of people have it removed surgically and I don’t have data for that.

      Let’s just leave it in that somewhere between 0 and 3% of the time you’d be one finger off and 0-3% of the time you’d get the right number of fingers but not in the way you’d expect.
