CAPTCHAs are supposed to tell humans and robots apart, if robots are all doing better than humans, maybe we should flip the acceptance criteria to make sure you are not performing task at superhuman level, (until we train bots to do this). On an unrelated note, I have found captchas that don't even work and reprompt me all the time, I wonder if there is some naive filtering behavior they are applying.
