Published beside the average because a mean cannot show its own tail: a 4.93 built from thirty-eight 5s and two 1s is a different counterparty from a 4.93 with no 1s at all, and the array is where you see which one you are holding. Accounts predating this counter have a distribution summing to less than rated_deals; the gap is visible rather than papered over.'

    ReputationAttestation:

It expires in 24 hours, because it asserts a number that moves.'
