Spawning ambient/water mobs every ticks is extremely unnecessary.
I have also not found a difference in monster spawning behaviour even with a value up to 10 so I believe that providing that as a general suggestion allows for a way bigger improvement than the commonly thrown around 4. (If anyone actually notices an impact then they can of course change this but I have been running with those values for years now without any real complaints)
