What are the rules for individual levels? I saw the one run in Saint-Lô had an in-video time of around 12:40 but the time is posted as the video length; is there any set of concrete rules for timing or is it simply how long the level lasts, including not being able to move at the start?

Edit: CotV's timing starts in the middle of the black bars moving out, even though you don't have control at that point, which is different from MrRacingmonster. I'll wait on your call before I submit anything.

Edit 2: Each level saves at the end, so timing could stop when that screen appears to make things easier. I suppose that might mean re-timing everything, though.

Timing is on first movement(RM's run was actually a 13:00 not 12:47 as his title said)

cotV's run was retimed to a low 7:16 so the timer on screen didnt really matter.

When does timing stop in this case? CotV's stopped when the black bars come in, but RM's first level run didn't have those. Sorry for all the questions.

losing control of your character, also yes RM run was retimed and ended once the screen switched to the loading screen since thats when you lose control.
