humping drywall
I am doing a 16"x6" drywall patch on a wall. I have used several coats of hot mud. The 16" horizontal edges are humped. Ive gone from hot mud to AP, for me, its much easier to control. Should I just make one pass to fill inside the humps, let it dry then feather it down out side of the humps? Im doing it in a cramped staircase with a light switch and a door blocking my outside passes and moving up and down a couple stairs to complete a pass. Too much sanding too.

I have a 14, 6, 4, and a 3. Ive been working with the 14. To set the tape I used hot mud, the 6" and a finger. The total area of the coats is 22x42 outside edge to outside edge now.

To late now but I for sure would not have used hot mud to set the tape.
A setting mud has an adhesive in it to help keep the tape stuck in place.

How wide/tall are the humps? did you have too much mud under the tape?
I've used hot mud on the tape coat many times with no issues - it's about the only way you can do repair work in a cost efficient manner.
I normally tape with a 3" or 4" knife, apply the 2nd coat with a 6" and finish with a 10" or 12" knife. On the tape coat you apply a thin coat of mud then press the tape into the mud using your knife to smooth it out and remove any excess mud.
It's hard to say what you need to do without seeing it. It might be as simple as sanding off some excess mud and then feathering the joint out ...... or maybe it would be better to rip off the tape and start over

I see three choices:
1 Sand down the humps
2 Fill in the voids next to the humps and feather the mud out further
3 Start over
You seem to have already rejected # 3.
