Records needed for this question
Population totals, data coverage and stratified error samples.
How to distinguish the two approaches
Separate excluded formats from clean records and document the basis for any extrapolation.
An illustrative review decision
If one service class lacks usable source data, disclose that exclusion separately from the reviewed population. A comprehensive file import should not imply equal review coverage across all service types.
What can lead to the wrong conclusion?
Sample error rates cannot be applied indiscriminately to dissimilar service classes.
The result to retain
A coverage statement that makes unreviewed exposure explicit.
