My tip is pull down the cameras every 2 to 5 seconds (you want to stay mostly in the office to save energy) if foxy is about to leave stay more active in the cameras (you dont need to look his camera just the cameras in general), dont worry for freddy moving quickly close the door when she laughs and moves to the right hallway, she will laugh again, fail the attack and go 1 room back (she can jumpscare very fast so be quick), bonnie and chica are mostly rng. I did this for night 7 and got to to 5 am consistinly the only problem was freddy music lasting less than 5 seconds
