in yuyu hakusho the bad guy completed something that takes 50 years of mental training to do in 8 years due to his split personalities splitting up the work between 7 of them
I didn't watch Yuyu, but in some other movies and series the personalities don't know about each other or they don't know what the other personality does so I was going by that.
If the two personalities know all about each other and are willing to cooperate then I say ok.
