This is a question which bothers me about any AI image generation, but here people are focused on doing humans so I feel it's a good place to ask as with humans it hits harder:

Let's assume I download a recommended setup and I'm a total noob sitting down to generate from a prompt. How many misshapen, badly generated disturbing chaos mutants from beyond reality do I need to see before the AIs return a somewhat satisfying result? Is an "unsuccessful image" just a person with a blurred face or somewhat off fingers, or are we talking about full-blown body horror?
