Comment on Facial recognition error: Customer misidentified by Sainsbury's
halcyoncmdr@piefed.social 1 day agoYeah, 0.02% of 65 Million is 1.3 Million possible errors.
And that’s just based on the raw population, that accuracy rating could be based on raw number of scans instead. A quick search shows Sainsbury’s serves 16 million customers a week. That’s 320,000 errors every week if the error rate is just raw scans as opposed to unique scans.

Your math is off, by two decimal places.

Indeed, it’s still a ridiculous amount of errors though.
65,000,000 x (0.02%) = 13,000 possible errors
16,000,000 x (0.02%) = 3,200 errors every week
