Zero-comment close rate(5.2.1)

Share of the tickets first delivered in the selected date range, each counted once per project on its first move into a delivered status (a ticket moved between projects counts in each project it was delivered in, with only the comments recorded in that project), that closed with no comment recorded in Jira at all. A closure without a recorded comment is not proof that no review happened, and trivial tickets often close without discussion; a high rate shows a reviewer where to ask how reviews are recorded. Counted over closures into delivered statuses only, under your organization's terminal-status settings (a MetaFrazo default applies until configured); zero-comment discards are backlog hygiene and are not counted.
