The Data score on Find cached phone

This score, out of 100, shows the share of people the call gave the right phone number for. We check each answer against the number in the person's email signature, never against another provider's answer. If a provider ran on fewer people, we compare it with how the others did on those same people. That way, easy cases can't raise its score. If we called a provider more than once on the same person, we score it on all those calls. That way, one run can't decide its score. Each provider here answers from its own saved copy of the data.
