I view the opening cutscene as the bedroom portion of Portal 2 intro cutscene, which isn't timed since you can't speed it up. The next map is where you first need to solve a test and therefore is the first time the run can be affected. It's also the first place the crosshair appears. I think we should also follow in Portal 2's footsteps by adding the cutscene time to our timers. (Intro cutscene is 6402 ticks or 1 minute 46.700 seconds )

Could we set the timer to start on map "sp_a1_pr_map_002", and/or "Time Travel" from the chapter select seeing as the first map is just a cutscene, similar to Portal 2's starting cutscene.

A cat in portal 1 that I’ve been running alongside some friends recently is rly fun. I call it Challenge mode all golds plus advanced chambers or CM all golds + AC for short. It’s basically what it says on the tin, it’s a run of all advanced chambers, plus achieving gold medals on All maps on all three challenge modes. I run the cat as inbounds no SLA but adding oob and inbounds sla would be okay too. My Pb:
