What about 88F for EVERYTHING!

More like it is essential for a new keeper to provide an optimal setup with gradients while they are learning (that's foolproof), keeping your animal with ambient temps alone is more for advance keeper that know how to recognize issues and can troubleshoot them on their own.

Additionally if you have 1 snake keeping the room temp at 85 would make very little sense, it would not be cost effective nor would you enjoy having your living room at 85.

Those are generally used by people with larger collection with a dedicated herp room.

100% this ^^^^^. If I only had a couple animals I would not be on ambient. When I went to ambient I knew my animals well and could tell if they were acting abnormally. I did not move my animals to ambient all at the same time. My isolation rack is still on heat tape. I spent quite a bit of time "adjusting" the room, placing the radiator, the fan, testing with a heat gun. What I did not talk about was redundancy. I have a backup heater set two degrees below the primary on it's own thermostat. Redundancy for cooling has not been completed yet and is a project for this summer.
