Users often catch what they see as conflicts, and you need to answer for this.

Often it's something as a different interpretation of data in multiple places (revenue in one place, profit in another) or differing date logic (one query includes a date in the range, others are "up to" that date, etc). Caching is another issue, especially if you selectively cache only slow queries.

To minimize this, always have an explanation on the chart/card (even if it's hidden but clickable to show)
