No not really: 
-Start ron
-start a level
-do as many things wrong as you can (kill everyone, let traps explode, kill your teammates)
-lowest score and time is important!

@Remiax for you im gonna do an extra slow speedrun one day :) <3

Yeah the score should count because your goal will be to get a low score so the time would make no sense

I was talking to a few guys and we were thinking about an F category, for fun were the goal basically is to score the lowest you can. What do you guys think about that?
