This v1 history holds the route, scanner method, browser, device, conditions, catalog, Brave-list source and list count constant. It does not hold the filter-list snapshot date constant: a changed snapshot can support raw and catalogued-service differences, but never a Shields or detector delta, so a difference here is not evidence that blocking behaviour changed. Differences can still reflect site experiments, ad rotation, caching or bot detection.

Evidence timeline

9 reports

No trend line: this site's newest measurement cohort holds only one report. 8 other reports were measured under different methodology generations, a different requested GPC condition and different tracker-catalog identities, so they are listed below rather than joined to one line.

Every retained report for ietf.org, newest first: its date, what kind of visit it was, its request counts as recorded, its third-party cookie count and its schema. Its request counts are lower bounds where the visit was incomplete.
