"Batches is hugely helpful in seeing the impact of changes I make to my prompts. Not quite the right term, but batch testing gives me more confidence in the statistical significance of the changes I make when I can see the output generated many times. If you're not batch testing your prompts, you're probably missing out on some low-hanging fruit."
