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

Which condition were you adding?
What operator was unclear?
What preview would have helped?

Author notes / illustrative keys where applicable:
1. Read for condition intent. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
2. Read for operator meaning. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for preview need. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
