If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

What group did the benchmark cover?
Which comparison condition was unclear?
What source detail was missing?

Author notes / illustrative keys where applicable:
1. Read for group scope. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
2. Read for comparison. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for source need. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
