Where are you from, killLogic? Your question forced me to download USA rom and its really faster than EU, i have run same level with 1m40s This is kinda stupid, but issue solved

Like you do realize that the faster you complete the stage in real time results in a higher in game time, right? It's counting down, not up. Yes, i realize. I completed faster, this is why at the end of level i had more time left on the timer. I had 1.17 and he had only 1:03. I saved more time so i was faster. Mayby my english is just bad and u cant understand me but i think i explained everything clear enough.

Ok, looks like i should explain better. Lets take 1st level as example. It started at 0:38 and finished at 2:30 on youtube. So it took 1m52s of real time to complete it. Lets look at in-game timer: it started at 3:15 and finished at 1:03. We have 2m12s of in-game time. Seems legit? I dont think so. So this is my run of 1st level: https://vimeo.com/247924704 It tooks exactly 2m. Lets check in-game timer: it finished almost at 1.17, so i spent 1m58s. Yeah, in-game time is not equal to real, but delta isnt so much. Lets compare times: His: 1m52s real and 2m12s in-game. My: 2m real and 1m58s in-game. So i completed level faster with 14s difference, but on video he is faster than me with 8 sec gap. Nice

I decied to speedrun Alien 3 on NES and found out that fastest run https://www.speedrun.com/run/kz5p97em just speeded up by 15 percent, so its real time is about 29 min. You can see it simply comparing in-game timer and youtube time.
