Using myself as a data point (self-diagnosed aspie / adhd), the key factors are:
do I have all the requirements / data I need—or is it obvious where I can find it?
will I be interrupted during my work?
If everything is clear and there are no interruptions, I could probably work 16 hours a day (assuming someone brings me food—or make it 15 hours a day and I will buy something myself).
But give me unclear or self-contradictory instructions, internal documentation written by people who hate to write, frequent meetings, two or three tasks to work on in parallel… and the number can drop to 0.
