I might not know what i'm talking about but after playing a bit i am %99 sure that under 5:30 is possible

I've never been into speedrunning before. But a couple days ago i remembered this game and how much i used to play it. So i got curious to see if it had a speedrun category. And i know there are only a few of you but WOW! this is so cool! Then i began to wonder: what IS the minimum possible time? Is a 5:30 possible? is a 4:59 possible??

From when i used to play it i remember there were quite a few exploits so as proper speedrunners i wanted to know what y'all thought the peak of this category is?
