By far the most interesting theory i have heard so far, compared to all the "speed matters on the random tiles" i have refuted many times with my 2-1 runs in the past.

Rest assured, it is random. When things are random and not going one's ways, one tends to try to find patterns. Maybe it's the current time that matters, maybe speed matters, what if i spin around in my chair twice and then pressing the button 10 times quickly?

All in all, it is a simple coin flip that can really go one way or another.

That said, if you can replicate this 50ish times in a row without any failures i might start trying to have a look at it myself. I was unsure whether they were random when i started too and tried to see if it really mattered, but in the end i just reached the conclusion that it's random and later when i asked they said random, so i'll keep believing it is random until someone can bring me proof that is more than "i did this 2-4 times and it was a great success!"
