It depends on your goal. Even with database schemas, iterating quickly optimizes for learning and skill improving. Aiming for quality tries to optimizes for creating a quality product faster. Still, taking some time for skill honing might be better than trying to design the perfect system on your first try.

I'd say it depends on your current skill level rather than on a task property like "strongly Markovian". Learning has diminishing returns. At some point more learning is not worth it anymore.
