I started my run a hallway away just like everyone else but mine got rejected. So, how is everyone else starting closer to the double doors than me. I watched every run on the leaderboard before submitting mine. If we're all starting a single hallway away how is mine wrong and everyone else's is right?

If we were all starting on a level playing field, we would all start the game facing the computer and have to complete the level from there but there wasn't a single video on the leaderboard that started that way. So, I moved myself one hallway away which is how every single video on the leaderboard started. How is everyone starting closer? And how is everyone facing the hallway when I start so much farther away and facing the computer?

Assuming it's the video on your Youtube page, you need to start in the starting room. Even from where you start you're 3 seconds closer than the short hallway. See my video for the correct start location. You may need to restart the game a few times to get the correct start point.
