What this actually means

medicare.gov recorded 106 fewer third-party requests in the visit configured for Brave-list blocking.

The visit with no blocking made 218 requests; the visit configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit) recorded 106 fewer third-party requests. The blocker directly stopped 14 requests; the remaining difference may include follow-on requests that never started once their sources were blocked, plus run-to-run variance. It also looks like 1 browser-fingerprinting heuristic matched.
