I don't think prompt / output ratio, is the speed to get the output that matters.

If I spend 1 hour and write 500 words of prompt to then attach X additional rows of data (e.g. Rows from a table) and the LLM returns X rows of perfect answers. It shouldn't matter that the output ratio is worse than if I had typed those characters myself.

The important thing is whether within that 1 hour (+ few minutes of LLM processing) I managed to get the job done quicker or not.

It's similar to programming, using LLMs is not necessarily to write better code than I personally could but to write good enough code much faster than I ever would.
