Prove it
Open any number and you get its trust record: the formula and its version, the numerator and denominator, the athena report to run, athena’s figure, the difference, the tolerance, who checked it and when, and where the data came from.
Where a definition changed after a month was published, the original published figure and the restated one sit side by side. A practice manager can take that page to athenaOne and check the number personally. Nothing has to be taken on faith.
