Some of those aren't quite independent evidence (clothing/hair/posture/body) but even assuming conservatively that they are, people who are trying can get 6–8 bits of evidence with some careful observation. And assuming correct calibrations on base rates, that's not good enough to clock someone. So I feel all right about this.
