keep the dead mod and monster spawn

[Kaos]

I am making a doom run with the Keep the Dead mod, and come across the bugged rune trial in argent tower. I passed it with the solution proposed by knightmare (set the persistence of the bodies low, so other monsters can spawn) and was able to finish it.

 

However, once completed the trial, I had the doubt that the game difficulty could be considerably lower because the monsters spawning are less than what I am supposed to get. 

Can this be confirmed or not? I feel like I'm breezing trough the game (at UV), even if it could be that after playing doom eternal, doom 2016 can be considered quite easier.
