Well I think I hit about 75% perfection, I was super tempted to alt-f4 as the final elimination screen was coming up, I regretted not doing so as soon as it passed the point of no return but it will have to be good enough for me in the meantime I guess

Total time loss due to errors, bad luck or reaction speed: ~24 seconds, which puts the possible run of this seed at about 4:23... I failed a run when the upload was at 95% completion at 4:17, so if it was clear it would have taken about 6 seconds to input the code (using the time it took to: input code and killself with end mission cutscene from this run as reference) which would have been a 4:23, which lines up pretty perfectly with the total lost time calculation I did funnily enough
