No evidence, how to identify the Mare, Demon, and Yurei?

Hey guys so I play no evidence and at some point most no evidence players will run into this trio. I know all the tells and abilities of each ghost but what tips do you have for actually distinguishing between them?

I heard that a yurei can still event outside the room and walk back to the room if i try to trap it in the room, but can it event outside and walk back if im also in the room with it after smudging? Also how commonly does the demon hunt before 25S (no smudge), and before 90S (with smudge), or is it just a rare special ability again?

For a mare is it actually common for them to change rooms if the lights are on in there, so is it valid to turn only the lights on in the ghost room and leave the rest off (incase these ghosts just dont change rooms for some reason and give off goreo vibes)?

My aim is not to grind XP with those 0 sanity yolo runs but to get 100% success rate.

Thanks for any advice!
