Yeah came here after sum similar. I didn't really want to look at any hints but Freddy has no type of signal and I end up using way too much power out of fear for her. You definitely should try checking on foxy consistently and just ignore Freddy until 5th laugh. If you check Bonnie often she tends not to move, however Chica will always be pretty aggro it seems. So that way, you can sort of get a flow. I'm no expert but I can make it to 5 am with like 40-30 power to spare on Freddy's shenanigans.
