A lot depends on the final colour and the opacity of the paint that you are using for the top coats.
If your finish colour is white then mist + 2 coats of super matt on the ceiling, mist + 2 coats of trade diamond matt in a hallway/bathroom.
Most of the finish colours I get asked to paint are F&B colours or Little Green, Designers Guild etc. I always get the client to order them from the manufacturer as getting them mixed in Dulux or Leyland etc can lead to disappointment. F&B stronger colours usually need a few coats for complete coverage. Little green will sometimes cover in 2. Designers Guild is a Mylands paint, I've not used their darker colours but the lighter ones have a nice base with good opacity.
My mate who has been a decorator all of his life gave me this advice once (and I have always used this method since with zero issues):
"If it hasn't been painted you need to put a mist coat on it (which is a watered down coat). It needs to be like coloured water (It will go everywhere!!!)
Ideally it needs to be a paint with out plastic in it, so a Dulux super Matt.
For the final coats you need somethin with plastic in it, like a vinyl Matt. I personally only use Dulux. "
