How these metrics are calculated

Shared rules (inclusive date boundaries, send-date attribution, unique vs raw counts) are documented once in How Analytics Metrics Are Calculated.
This is the same definition and reply-date axis as the headline tile (overall-stats-v2). Because each positive lead’s reply falls on a single date, the daily values here sum to the overall range total for the same window. (If you instead want positives attributed to the day the email was sent, use the by sent time variant.) positive_replied is a distinct-lead count. The lead category is mutable, so re-categorising a lead changes historical days. Dates are inclusive on both ends, and a single date returns that one full day.
