IIRC it has to do with a standardized shifting procedure for test purposes, which ignores some differences between so many engine configurations. Then it led to close-ratio manual transmissions becoming more widespread, even though their gear-spread may be more suitable for a "sporty" driving mode than to improve efficiency.
