My Suggestion: Start: After the Lantern Symbol Pops up in the Loading Screen after Starting a new Game End: After the Screen goes black after the final Cutzene

As far as i know ppl have already developed an autosplitter that looks at certain ingame variables to start / pauze / stop the game. You can find the files for that in the discord and i believe it will be available in autosplit before the leaderboards open. I hope someone else of the community can confirm?

Correct, timing starts once the lantern flashes in the corner of the screen after the initial load. Timing stops once you push away the rocks to escape the bunker. Using LiveSplit's autosplitter this will all be automatic.

The time starts right when you see the message "You are now on your own learn, adapt, expriment and survive" And the time ends as soon as Henri starts the falling animation or as soon as you cant move after pushing the rock out of the way.

Incorrect. The timer starts approximately 4.2 seconds prior to that message appearing, like I stated above. Again, please make use of the automatic start/stop feature in LiveSplit that our lovely PrototypeAlpha and Sychotix have developed for the community so that this process is as seamless as possible for runners and verifiers alike.
