-        <p>Lifetime stats combine saved telemetry from Black Ops I and Black Ops II, including active and interrupted games.

         <p>Highest reported score is the largest observed points balance, not total points earned. Completion requires the player to appear in the final report. Records stay with the same GUID across both games when a player changes names, and the latest reported name is displayed.</p>
