If you wanna know a strategy I used to win here is what I did.
At the beginning of the night I switch the camera to The Booty Cave and dont switch off from it for the rest of the night. If you catch her running to your door on the camera's before closing the door, she dosent take that much power.
Freddy will laugh 5 times before being at the camera near your door. Close the door until she laughs again. She will now only be at 2 places for the rest of the night either being in the closet or by your door.
Bonnie and Chica you dont have to pay attention to because if you have your camera down and check the hallway with the lights, you will hear their footsteps or see them when you flash the lights. They usually go away quickly after you close the door.
As for the 92% I have that same percentage too and I beat 4/20, I believe I just have to be caught by Golden Freddy in the office to complete it, but apart from that I have no clue how to get 100%.
Good Luck
