It would seem as if the lbFastestCompletionMs stat for the clan leaderboards includes times for events that were not completed (such as when happens when a fireteam is returned to orbit after all dying in the prestige nightfall).
This has not been tested for all game modes but it certainly seems to be true for modes 3 (Strike), 16 (Nightfall) and 18 (AllStrikes).
