We can't 100% be sure that the run was performed in a single segment or that it wasn't interrupted in the mid. There are way longer runs on this site

Breaking my no forum posts streak just to put a moron down...

If we don't really care about video for 1, why would we care about it for 3? This series already has a good in-game timer that displays useful things about progression (location, team, watch rank).

And since when were there rules dictating runs of this game have to be single segment? This run is already niche enough, most people don't have good recording equipment and/or are capable of running for 8-10 hours straight.
