## Author notes / illustrative keys where applicable

1. Read for gap interpretation. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
2. Read for legend need. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for explanation. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
